Files are skipped by mistake in project request (invalid targets command search)

[operasfantom]

Steps to reproduce

1. Open and configure project c-algorithm
2. Choose target libcalg.a
3. Generate tests for projects
4. Some files are skipped by mistake
5. See logs

Hint

There are two identical libraries libcalg.a and libcalg.so which are built from the same sources but different object files. This is very common case in real projects. As for now, Linker works with the whole BuildDatabase when linking files for target and as a consequence uses non-existent files when choosing bitcode files. This can be fixed by restricting BuildDatabase to the subset of files for target.
