gajim remove ressources from jid when using Actions/Start chat
Jabber.fr server propose a echo module used to test messages sending. You can simply send to jabber.fr/echo, and the message is bounced back. It work when using "send single message", but not with "Action/Start chat".
It seems gajim remove the ressource part of the jid, and this is quite annoying. If someone specify the ressource, it should not be silently removed, because user is likely have a good reason to specify it.
It seems to comes from [6046].
I suggest to revert this commit, and to explictly remove ressources before calling the function new_chat_from_jid when needed. There is only 4 places to look at in the code, so this should quick.
