This reverts commit da8cb1a.
It turned out that da8cb1 actually changed the API of python-mpd: if an error
occurred while connecting to the MPD server, MPDClient._connect_tcp() would always
return 'ConnectionError("getaddrinfo returns an empty list"), even if getaddrinfo()
actually returned something.
I have no idea how to make getaddrinfo() returns nothing, so it's hard to test at
the moment.
