…on an reraise them. Fixes quodlibet#2705

Exceptions raised during signals don't bubble to the test caller, instead they
get pushed into sys.excepthook which by default prints them.

This adds a pytest plugin which wraps each test (I think..) collects uncaught exceptions
and reraises them at the end.

This uncovers a few bugs, so this makes the tests fail atm.

9 tests are failing due to this, better look at it before 4.0.1

Cool. I've noticed this problem a couple of times too actually - adding a test that "fails" but only if you look at debug logs a lot...

This uncovers some bugs in the playlistbrowser tests. Most of the inherited tests were
failing, and I think they never passed, so just remove the inheritance.
