Test end-date, not just its string representation, in QDTE test

In tst_QDateTimeEdit::dateEditCorrectSectionSize(), only the final
displayed date was tested; many of the tests checked day of week (by
name), which might well match despite actually selecting a different
date than the one intended. So test the date is as expected, too.

In the process, tidy up the code, give values more informative names,
turn a trivial static function into a lambda.
