Fix focus_follows_mouse over swaybar

If you moved your mouse over swaybar (e.g. to scroll between
workspaces), focus would move to the workspace. This is not the right
thing to do. The solution is complicated by the fact that if you move
your mouse into a new output with an empty workspace, that workspace
_should_ receive focus.
