wayland: don't try to use seat devices that aren't (yet) present

Browse source 
Before commit ac448bd42b the pointer,
keyboard, and touch objects were initialized when the seat was created.
Now they're initialized later, when the clutter device manager finds and
loads them.

This commit makes sure we don't try to access those objects if they
aren't initialized.
