Jonas Ådahl 6841153ad7 tests/kms-device: Add test for scheduled no-ops
We can schedule an update from the cursor manager, but that doesn't mean
there will be an actual plane assignment changed at the time of the
update processing, since for example we might have "touched" a CRTC, but
already left it before the processing started, meaning we have nothing
to change after all.

Add a test case that checks that this works properly.
