placementtracker: fix some windows not being restored

Browse source 
If a window was moved by the user, it got effectively blacklisted from being
ever restored again. Instead of only tracking the last restore point, compare the
current window state with the state it had when the output configuration was last
seen. If either that or the last restore point match the window, restore the old
window state.
