MUC: Don't default room name to JID localpart (API breaking change) Behavior with turning empty name into localpart was originally introduced in 711eb5bf94b4 This has caused some problems for clients, making it difficult to differentiate between a room actually named like the localpart from a room without a name. Breaking: The function signature of the :get_name() method changes from always returning a string to optional string.
