Avoid selecting profile suggestion if Ctrl+Enter is pressed

If I was typing a queet and ended with a mention (@theru) it listed
several nicknames matching '%theru%', such as 'anoTHERUser'. When I
send the queet with the short command Ctrl+Enter it chose @anotheruser
and my friend theru was ever so sad not to receive the notification :(
