fix: inner_configure: Check Config::OnlyFetchMvbox before MvboxMove for multi-transport (#7637)

`Config::OnlyFetchMvbox` should be checked before `MvboxMove` because the latter makes no sense in
presense of `OnlyFetchMvbox` and even grayed out in the UIs in this case. Otherwise users will see
an error mentioning the wrong setting.
