spack.yaml installed entirely from buildcache `reuse: true` results in ghost specs

### Steps to reproduce

Installing this small spack environment entirely from buildcache results in some packages depending on ghost specs. What I mean by "ghost" spec here is that some specs get installed which depend on non-installed dependency specs! This creates issues with generated module files, for instance, where loading dependents of the ghost spec results in attempts to load the non-existent dependency's modulefile.

I've wiped out my spack install entirely and re-installed the environment here a couple times. The first time there was a ghost glibc. The second attempt at wiping+re-installing resulted in the prior missing glibc now being installed, but now there was a ghost libxml2.

* [spack.yaml.txt](https://github.com/user-attachments/files/18652370/spack.yaml.txt)
* [spack.lock.txt](https://github.com/user-attachments/files/18652371/spack.lock.txt)

For instance, here is how I installed this environment:
```
$> spack -e . concretize -f | tee concretize.log
$> spack -e . env depfile -o Makefile
$> export SPACK_INSTALL_FLAGS=--cache-only
$> spack -e . buildcache keys -it
$> make -j -k SPACK_COLOR=always --output-sync=recurse
```

The concretization log shows four `libxml2`'s in the DAG:
```
$> grep "\^libxml2 concretize.log
 -   3juct62              ^libxml2@2.13.5%gcc@10.5.0~http+pic~python+shared build_system=autotools arch=linux-centos7-x86_64_v3
 -   etomzyn      ^libxml2@2.13.5%gcc@10.5.0~http+pic~python+shared build_system=autotools arch=linux-centos7-x86_64_v3
 -   qxbwyas      ^libxml2@2.13.5%gcc@10.5.0~http+pic~python+shared build_system=autotools arch=linux-centos7-x86_64_v3
 -   lmh2pr7              ^libxml2@2.13.4%gcc@10.5.0+pic~python+shared build_system=autotools arch=linux-centos7-x86_64_v3
```

With the environment installed, only three of these `libxml2`'s were installed:
```
$> spack find -l libxml2
-- linux-centos7-x86_64_v3 / gcc@10.5.0 -------------------------
lmh2pr7 libxml2@2.13.4  qxbwyas libxml2@2.13.5  3juct62 libxml2@2.13.5
==> 3 installed packages
```

Note above we are missing `libxml2 /etomzyn`. But `libxml2 /etomzyn` has installed dependents!
```
$> spack dependents -i /etomzyn
==> Dependents of libxml2@2.13.5%gcc@=10.5.0/etomzyn
-- linux-centos7-x86_64_v3 / gcc@10.5.0 -------------------------
trjllzb gettext@0.23.1  drqlymo hwloc@2.11.1  j3ch2pk llvm@17.0.6  xxonzxz llvm@19.1.7
```

Thus, if I generate modules and then try `module load` for one of the dependents of this ghost `libxml2`, we see the following errors:
```
$> module load llvm/19.1.7
Lmod has detected the following error:  The following module(s) are unknown: "libxml2/2.13.5-etomzyn"

Please check the spelling or version number. Also try "module spider ..."
It is also possible your cache file is out-of-date; it may help to try:
  $ module --ignore_cache load "libxml2/2.13.5-etomzyn"

Also make sure that all modulefiles written in TCL start with the string #%Module

Executing this command requires loading "libxml2/2.13.5-etomzyn" which failed while processing the following module(s):

    Module fullname       Module Filename
    ---------------       ---------------
    hwloc/2.11.1-drqlymo  /storage/upack/spack-tools/spack/share/spack/lmod-modules/linux-centos7-x86_64/Core/hwloc/2.11.1-drqlymo.lua
    llvm/19.1.7           /storage/upack/spack-tools/spack/share/spack/lmod-modules/linux-centos7-x86_64/Core/llvm/19.1.7.luaExecuting this command requires loading "libxml2/2.13.5-etomzyn" which failed while processing the following module(s):

```

Oddly, if I query Spack for the installed dependencies of `llvm@19.1.7` it shows `libxml /etomzyn` as installed!
```
$> spack dependencies -i llvm@19.1.7
... etomzyn libxml2@2.13.5 ...
```
