Fix memory leak in QDomDocument entity text expansion
The created entity node's reference count needs to be decremented to 0
before it is added as a child, because appendChild will increment the
reference count to correct value of 1. Re-enabled commented-out test
data of tst_QDom::setContent to exercise the code path with the leak.
