[tests] Don't import QUnitTestCase into tests' global namespace
Unittest's test loader will try to execute QUnitTestCase's test_javascripts method. However this class is intended to be subclassed, not to be executed directly.
This change has the following consequences:
* slightly faster test execution
* almost all rtags warnings are gone
