tst_QFrame: fix memleak in testPainting()

Browse Source 
Similar to 5be58ac9271555eed3a2884d827f30c164d2277d for tst_QWidget,
this test leaked the result of QStyleFactory::create() and the fix is
the same: cache across the test function calls. This time, it's for
performance; there's like 50 different data tags for this function...

Amends a8723871ee7125b97ce5467b94198e93a528c960.
