REVISION SUMMARY
  When running ctest in my session a few OpenGL/waylandonly tests crashed
  on tear down. This does neither happen on build.kde.org nor when running
  ctest in a tty. Comparing the env variables of tty and session pointed
  to the session variables. Unsetting those makes the test not crash. This
  makes sense as e.g. plasma-integration no longer gets loaded.
  
  As our test suite is intended to test KWin and not plasma-integration or
  gnome integration we should have a clean and reproducable environment,
  so the variables are unset.

TEST PLAN
  100% tests passed, 0 tests failed out of 130

REPOSITORY
