Update screen pool connector ID ordering before adjusting desktop containments
Setting the screenpool primary screen changes the mapping of ID ->
connector. We need this to be done before the
DesktopView::setScreenToFollow is called because otherwise it will save
lastScreen with the wrong ID.
Hot swapped primary, both things swapped.
Things restored as I think they should be.
