fix: problem unwrap in wl_pointer::Event (again)

Browse source 
I triggered the unwrap in the `Motion` case while using the color picker
in Krita. If you hold down the mouse such that the color comparison
pop-up opens and flick to it, you can sometimes enter and motion on a
stale surface. Somewhat inconsistent to trigger.

I also removed the unwrap in the `Button` event since it is logically
equivalent to the other unwrap. A few logging statements also got
changed to give wl_surface details.
