Fix missing channels

[jbcpollak]

On our private instance we discovered that some channels were missing when we used /list-private.

After digging in I found that the groups api was deprecated in favor of conversations. I fixed it to make it work, but for my own familiarity I bumped the node dependency version up to 10.x and used async/await. I hope that’s ok, or at least this can be a template for fixing the problem as you desire.

this is great, also bumping the node version, so that other people can clone this more confidently

This looks good as far as what's changed — did you spend any time looking at other things affected by the slack module upgrade?

I didn't specifically review API changes but I do know we ran / are running this modification in production on our local slack with no issues. I'm no longer at the company but as of December 2019 we had no issues with the bot with this change.
