virtual-device: Process supported commands on device open

Browse Source 
When opening the device we can process commands that we left for that
after the previous close, to do that we only have to inject an invalid
command that will be processed (and ignored) while closing, so that at
next device opening we will be able to proceed with the previously
sent commands.

Add tests to finally check this case!
