Reload when the connection drops instead of reconnection + `setState`.

[allisoncorey]

Ideally restoring the socket.io connection and processing the setState would resync properly, but:

• setState doesn't replicate deletions yet.
• There's a greater chance of error if drivers don't handle all of the changes correctly.
• The ruby socket.io doesn't correctly implement the protocol for a client to reconnect using its original ID.
