Improve logging around listening services

Browse Source 
I wanted to bring listen_tcp into line with listen_ssl in terms of returning a
list of ports, and wanted to check that was a safe thing to do - hence the
logging in `refresh_certificate`.

Also, pull the 'Synapse now listening' message up to homeserver.py, because it
was being duplicated everywhere else.
