AutoTest: Improve run and debug under cursor

Especially when running tests that are not macro-based
(e.g. QTest) it could happen that more functions had been
executed as the filtering only applied when the cursor
was located at the definition of the function.
Try further filtering using the code model to avoid running
functions that match by name, but are located in a different
class.
