Fix usergroups.users.{list,update} and files.commnets.{add,edit,delete} APIs

[masatomo]

Some Slack APIs has 2 dots like usergroups.users.{list,update} / files.commnets.{add,edit,delete}
These APIs didn't work and this patch fixes it.

Make this look like the other entries please, quote the methods and add your - name. at the end.

Do I understand correctly that the implementation here of files_comments is actually not an API, the API is files_comments_edit and such? That makes sense, so the only problem in this PR I think is the command line implementation where you want files comments edit kind of API.

Right. refs. https://api.slack.com/methods/files.comments.edit

Also, I've updated everything you pointed out.

Nitpick: Missing period at the end.

Please check the build, you have to fix rubocop at the very least, run rubocop -a, then rubocop --auto-gen-config for everything else. Squash your commits. Thanks, this is close to be merged.

[masatomo]

ok. but seems robocop -a updates many files which I didn't touch for this pull-request. do you still want me to run it?

[dblock]

It shouldn't but yes, @masatomo, just make the build pass and then we shall see :)

[dblock]

The period is in the wrong place, should be at the end of the line :)

[masatomo]

seems rubocop verison in trivis-ci is older than mine what do you want me to do?

[dblock]

It uses what's inside Gemfile.lock, you probably have a global version and would need to run this with bundle install. I'll take care of this, no worries.
