fix subdirs of tests/ being included in the report

[Maestro-Zacht]

Description

Currently if there are test files in a subdir of tests/ they'd be included in the report. For example:

tests/
    dir_a/
        test_a.py
    test_b.py

in this scenario, tests/dir_a/test_a.py would be included in the coverage report.

Nice catch, but wouldn't it be easier to simply exclude */tests/*, so everything in any tests directory is ignored?

I've never looked at that file, as I never had any issues with it, so I don't know if that would be sufficient.

Same, I also never looked at it and I only noticed this because of some test files appearing in charlink reports. I didn't think about ignoring the whole dir, I just checked and it still works. I'll make the change
