Adding subproject causes setting to no longer be evaluated (?) #7173
Description
steps
sbt 1.8.2
val foo = project.in(file("foo"))
val fooAux = project.in(file("foo-aux")).settings(foo / Compile / sourceGenerators += Def.task(Seq.empty))
val bar = project
val baz = projectproblem
Project foo has no source generators.

expectation
If we remove the baz project from the build, then foo does have a source generator. This is what I expect.
