Fix an assertion failure in massageAdjustedDateTime()v6.2.36.2.3
The QDateTimeData &d it's passed is a copy that's about to be modified; before we do so, we haven't detached so its internals have a ref-count of two, contradicting an assertion in the non-const Data::operator->(); so just directly access d.d->m_timezone, since we know that spec == TimeZone implies !isShort(). Added test that triggered the assertion and now doesn't. Fixes: QTBUG-99668 Change-Id: I07321ad91be5adce524be18e4ab82eee7110dc6a Reviewed-by: MÃ¥rten Nordheim <marten.nordheim@qt.io> (cherry picked from commit 5d228beb520d92c985497fb43fa91d2920db6cb0)
