Use SUCCEED macro to report Ok results failures to Catch2

The previous approach buries the list of which trompeloil requirements
were matched in the expansion of the REQUIRE expression:

PASSED:
  REQUIRE( trompeloeil_mock_calls_done_correctly != 0 )
with expansion:
  "spy.rowsAboutToBeInserted(QModelIndex{},1,1)"
  !=
  0

Using SUCCESS puts the real message up front, with no extra quoting.

 PASSED:
with message:
  spy.rowsAboutToBeInserted(QModelIndex{},1,1)

SUCCEED has been available since Catch2 1.2.0
