Marc-André Lureau 7c877c8030 tests: Remove test cases for alternates of 'number' and 'int' 
Alternates with both a 'number' and an 'int' branch will become
invalid when the next patch merges of QFloat and QInt into QNum.
More sophisticated alternate code could keep them valid, but since
we have no users outside tests, simply drop the tests.
