Fix access to uninitialised memory that might lead to crashes
QMetaObject is POD, so its constructor is implicit and trivial
(doesn't initialise anything). QAbstractDynamicMetaObject doesn't add
a constructor, so the QMetaObject sub-object remains
uninitialised. The users of either class must ensure they initialise
the members if they will be accessed.
