MEDIUM: server: server-state only rely on server name

Since h7da71293e431b5ebb3d6289a55b0102331788ee6as has been added, the
server name (srv->id in the code) is now unique per backend, which
means it can reliabely be used to identify a server recovered from the
server-state file.

This patch cleans up the parsing of server-state file and ensure we use
only the server name as a reliable key.
