This should be fixed now. Thanks for the report Arfrever and the analysis Ghost. I still get these warnings, but they are discussed in Issue 18383:

Warning -- warnings.filters was modified by test___all__
Warning -- warnings.filters was modified by test_warnings

----------
resolution:  -> fixed
stage: commit review -> resolved
status: open -> closed
