fix intermittent test failure

For some reason, the parser stopped working intermittently, even
though the format has been the same since aapt 23 or earlier.  Then
also, some of the test cases pointed to symlinks that were no longer
generated, and one test app now has a blank versionName.

Strange that this wasn't caught in the gitlab-ci runs.  !484
