Ctrl+A shortcut when "Single window for everything" selected does not work as expected
Reproduction:
- put Gajim is in "Single window for everything" mode
- put focus on message textview or chat history (i.e. start writing a message)
- hit Ctrl+A
Expected: select all text in message textview (or whole conversation history in chat window).
What happens: Gajim pops-up 'Accounts' window. This is because shortcut is taken from roster window and as chat window and roster are the same window here, standard shortcuts are overridden for whole chat window also.
