device-monitor: fix device listing without --follow

Browse source 
In !427, I removed the call to get_devices in order to always
print added devices from the bus handler, however this requires
the main loop to run until all pending messages have been consumed.

This commit achieves this by always running the main loop, and
simply adding an idle source to quit it in the non --follow case.
