Running the server and specs fails for ActiveRecord based sample app

Problem

Seeing this error when trying to rackup and also running specs for active record sample app:

Failure/Error: require 'slack-ruby-bot-server/rspec'

Possible Cause?

Looking deeper it seems maybe with grape-1.2.2 adding SortHelper in

slack-ruby-bot-server/lib/slack-ruby-bot-server/api/endpoints/teams_endpoint.rb

Line 7 in 79313f7

helpers Helpers::SortHelpers

doesn't seem to add sort method to the endpoint.

Interesting, sort was a class method. It's probably a regression from ruby-grape/grape#1803. You (or someone) should try writing a spec in Grape for this. We should be fixing it.

I think it's not Grape issue, or im getting the issue wrong :)

Looks like in this repo we are trying to add sort method to the endpoint in SortHelper here

slack-ruby-bot-server/lib/slack-ruby-bot-server/api/helpers/sort_helpers.rb

Line 37 in 79313f7

def sort(coll, options = {})

and somehow adding SortHelper doesn't add sort method to the endpoint

Fix in #89.
