SLACK_CHANNELS is set but channelName is null

[moet78]

Hit this error when starting corebot. I have specified SLACK_CHANNELS but it complains about null..

Is there some other thing that needs to be specified?

You can set SLACK_ENABLE_JOIN_MESSAGE to false to bypass this bug...

The actual bug is on the slack-simple-api project.

Corebot needs to replace slack-simple-api with https://github.com/seratch/jslack-maintenance-releases

Thank you - raised #69 to look at replacing the library.
