Can't join muc with same jid although not subscribed to in roster
Bug description
When trying to join a muc, i get the misleading alert that this is not the name of the chat.
german: "Dies ist nicht der Name des Chats"
After removing an accidentally added contact from the roster having the same jid as the muc-jid joining the room works fine.
Steps to reproduce
In roster go to menu "Action"->"Start chat...".
Paste full jid(e.g. gajim@conference.gajim.org) of chatroom and apply.
Open menu "Action"->"Join groupchat..."->"Join groupchat...".
Paste jid into inputfield labeled "Chatroom" sothat it sorts out room and server.
Apply Dialog.
