libnm: add a test for connection-deleted-while-being-created

Browse source 
Since NMRemoteSettings doesn't announce new connections until it has
fetched their properties, it's possible that a connection could get
deleted while we're waiting for it to be created. NMRemoteSettings has
code to deal with this, so add a test to make sure that it works.
