IDLE code receiving responses for other operations

[petersondrew]

After the changes to the IDLE code, the IdleResumeCommand function in ImapClient is throwing exceptions on some operations (like MoveMessage). This seems to be because that code is catching the responses for the other commands (EXPUNGE for MoveMessage, I've also seen OK SUCCESS).

Is it really necessary to throw and exception if we don't get the response we were expecting? It seems like since we don't do anything with the response, it's pointless to throw an exception.
