Move some tests of QTimeZonePrivate::isValidId() to where they belong

They were tucked away in the back-end of the isTimeZoneIdAvailable()
test, but a separate isValidId() test had been added more recently,
which made some (arguably all) of them redundant. Reworked this test
in the process, so that the QSKIP() happens in _data() once instead of
in the test that's never run because there are no data rows.
