tests: restrict pytest test collection to kallithea/tests When the kallithea root directory contains a populated virtualenv, pytest would also collect tests in python packages installed there. Restrict the tests to be considered to any test_*.py file inside kallithea/tests. Additionally, by renaming unwanted test files in kallithea/tests/scripts to _not_ match this pattern, we can completely get rid of the 'norecursedirs' option.
