Add skeleton unit tests for QEntity and QAspectEngine

QAspectEngine is crashing upon shutdown so adding a test case to
investigate. Without a root entity set we just get warnings about
threads being killed whilst still running. With a root entity set, it
crashes. Need to solve these before we can test any more work towards
a clean shutdown. Next commit solves the crash so merge it together
with this one.
