undefined method `parser' for Parser:Module after bumping parser dependency to 2.6

[michaltrzcinka]

Describe the bug After upgrading parser dependency from 2.5.1.2 to 2.6.0.0 (because of Rubocop upgrade), I started to see the following errors from my test suite:

  Failure/Error: klass.parser.parse(klass, connection.run(type, path, params, headers))

     NoMethodError:
       undefined method `parser' for Parser:Module

To Reproduce Steps to reproduce the behavior:

1. Upgrade parser dependency
2. Run any code which uses included_data.rb

Expected behavior No error should occur.

Additional context

My guess is that JSON-API Consumer is incompatible with the new version of parser gem, which came out yesterday.

Actually, the problem persists even if I fix the parser dependency to 2.5.1.2. So the problem seems result from Rubocop upgrade - from 0.58.2 to 0.60.

@michaltrzcinka I am in the middle of moving overseas. Could you take a stab at a fix? If you cannot, I should have time to get to this in a few weeks.
