wayland: prefer a manually requested size over the configure hint

Browse Source 
When a window receives a resize request, it might ignore this new size and
use the compositor's size hints instead to restore to floating mode.

This commit changes that behaviour in that a window will always prefer
the manually resized dimensions over the compositor's hint.
