when using single window interface, double click on a roster item doesn't give focus to text input
so: with just the roster window (no chat tabs):
write Yann ENTER
Then write: Hi Yann!
Hi Yann! is accepted by the roster (and a lookup on the roster items is performed).
I tried to fix and ended up in nowhere because I never liked the fact that MessageWindow and MessageControl and all that were either complex or lacked good documentation
anyway I just commit #FIXME: #10264 (closed) hopefully travis or someone that understands it fixes this. (also please document the damn API :#)
