Relates to #3795 (and #3791) and also #3288.

I suspect the fix is to reproduce whatever #3288 did for the build command but for ghci.

Steps to reproduce

Easiest to check out dbaynard/issues@2530d18 (internal-libraries branch) and run stack ghci.

Alternatively, create a package which has an internal library module and attempt to import that into that package's own library or an executable (they have the same outcome).

Expected

stack ghci loads the repl.

Actual

Error message, for internal library named internal

<command-line>: cannot satisfy -package internal

Note, stack build is successful. Also, stack exec -- ghci loads correctly (though doesn't load the packages).

The full output is in the readme in the internal-libries directory at the dbaynard/issues github repo, above.

Stack version

I merged fix-ghci-autogen-path-3791 (030a442) into master (
