Fix QMetaMethod::invoke and automatic type registration

This was simply not working for two reasons:
 - The index passed to QMetaObject::metacall was not right (there was an offset
   because of the return type)
 - If the registration succeeded, the arguments were not even initialized.

The tests in tst_moc always called QMetaMethod::parameterType before calling invoke,
which was properly registering the type. So this was not seen in the tests before.

[ChangeLog][QtCore][QMetaMethod] Fixed crash in invoke() with QueuedConnection and
types whose metatype gets automatically registered.
