tests/backend-test: Wait for stage update in add and remove_device

Browse Source 
We put a DEVICE_ADDED or DEVICE_REMOVED event into Clutters event queue
here, so we should also wait for Clutter to process events once.

Just putting an event into the queue doesn't mean it gets processed
immediately (especially when the commit after this one is applied), so
wait for a stage update here.
