Fix empty pkginfo_repo_path GoogleDrive

[reneski]

If GoogleDrive.munki.recipe is executed but the same App version is already in the munki repo it returns an error that no pkginfo repo path is set:

With this commit (thanks to gerardkok) it stops the process without an error:

Handled this differently per 34dcc206d66da58be64a180ae37173bf51c6e1a8. This instead checks if we've actually imported something, and only then do we try to update the receipts.

Confirms on my end this works as expected.
