Show full and correct JIDs in the "Accounts"-window and rooster
Current situation in Gajim 0.99.2: Instead of the full JID Gajim only shows the servername for an account in the "Accounts"-window, so instead of firstname.lastname@example.org it only shows musterserver.de. That in itself is insufficient already!
That behaviour then creates an even more dramatic UX-problem as soon as the user creates another account on the same server, for exmaple email@example.com. If Gajim would at least behave logically the user would see two accounts both named just musterserver.de which as a result would make the user unable to differentiate between the two accounts without having to click on one of them. Gajim though does the mistake and puts a number behind the servername of the second account, so in this example an account would show up as musterserver.de1. So the endresult is that it shows a wrong servername!
