[quarkusio#36582] Fix bug: TransactionalUniAsserter never fails

TransactionalUniAsserterTestMethodInvoker is a subclass of
RunOnVertxContextTestMethodInvoker.

The problem is that there were two separate pointers keeping
track of the asserter in the superclass and in the subclass.
This lead to only one pointer being initialized and, if the wrong
pointer was null-checked, the asserter was ignored causing the test
to never fail.

This commit fixes the issue by keeping only one reference to the
asserter in the superclass.
