Keep relay buffer when clicking on the nicklist

When clicking on a nick on the nicklist, the `/query` command is issued, causing the relay to switch its buffer to the query.  weechat-android should switch the *client* buffer instead (see ubergeek42#538), but leave the relay buffer intact.
If the relay buffer is switched, it may cause missed notifications due to weechat  incorrectly believing that messages have been seen on the relay, since the buffer is opened.

Fixes ubergeek42#550
