AutoTest: Widen scope for run under cursor

..and debug under cursor for QtTest and GTest.

Depending on the information coming from the code model
we may be able to get a correct scope even when standing
inside the function that is defining the test.
This makes more sense than the original behavior which
made it a hard requirement to stand on a literal to
run or debug a test under cursor.
But as the codemodel does not provide usable information
for all frameworks keep the original behavior as fallback.
