Don't query for metadata on playing status

These removed lines of code were for a problem that no longer seems to
exist with other phones. It was a band-aid at best, having us pull
metadaa on 'playing status' when a phone really should have just been
sending the update to us anyway. Pulling metadata here causes a bad user
experience with cover artwork where the new metadata is interpreted as a
track change in Java land and cover artwork can be redownloaded. This
happens primarily with non-database aware players after a BIP reconnect
where we're guarenteed nothing about the handle we receive.
