Resource change needs account to be deactivated/reactivated
I have found a new bug:
1/ Connect an XMPP account
2/ Look the resource/priority in XMPP Account group tooltip (it is not in self-contact tooltip)
3/ Disconnect the account
4/ Go to Settings of same XMPP account and changes the resource name "gajim" by "gajim.test" (for example), close the Settings window
5/ Reconnect the same XMPP account
6/ Look the resource/priority in XMPP Account group tooltip (it is not in self-contact tooltip) : It is always same, the old resource name (not the new resource name)
PS : If we change the resource name with a connected XMPP account, and when we close the Settings window, there is a Re-login request dialog window, if we Re-Login, after the reconnection, the resource name has been changed.
