assignment/comment/watch does not work

[davidkarlsen]

I can search and create issues, but watch/add comment/add label does not seem to work. Example:

ec 11 2017 10:23:25 GMT+0000 (UTC)] DEBUG Received message: 'hubot TACJFRSR-172 watch' in channel: DM, from: david.karlsen

but when I check the issue log no changes have been done / watchers have not been updated

It seems these command only work in context of a channel? I am having a hard time understanding https://github.com/ndaversa/hubot-jira-bot/blob/master/src/jira/comment.coffee clearly
