Title: Improve tab completion for /topic

Currently, /topic works rather strange and sometimes it doesn't complete this
command at all (/t however works fine in those cases). This patch enables the
following logic: complete topic by its first letters, for example if a channel
has a topic named `example` then something like `/topic ex` is completed
but not `/topic oth`.
