Full modulepath not ending up on report-files

[casparvl]

Checking the report files, I see:

          "full_modulepath": "['']",

for e.g. an OSU test.

The full modulepath is supposed to be resolved and logged here.

It seems that the extraction of this string doesn't work because it simply doesn't end up in the output:

EESSI_CVMFS_REPO: /cvmfs/software.eessi.io
EESSI_SOFTWARE_SUBDIR: x86_64/amd/zen2
FULL_MODULEPATH:

I.e. this echo somehow returns nothing.

Note, we could probably improve on that code as well. We now print based on module_name, but might want to print based on modules, the list of modules that ReFrame loads, and then also make the full modulepaths a list of full modulepaths to which these are resolved.
