wayland: Only restore windowed constraints in configuration events

Browse Source 
In some cases, the fullscreen deadline handler can be hit before the associated configure event is received, resulting in the constraints being erroneously restored. The state is doubled buffered, so it shouldn't interfere with the pending fullscreen dimensions, but it isn't correct behavior.

According to the spec, calls to set/unset fullscreen will always have an associated configure event, and the constraints will be reapplied as needed there.
