Fix code climate reporting in travis

[ghost]

I stumbled upon your project when looking for examples of how to integrate code climate, and tried copying your configuration. Unfortunately it's only 99% correct and the data is not being submitted. Updated the travis config to make it work.

Current output:

Submitting payload to https://codeclimate.com... 401 Client Error: Unauthorized for url: https://codeclimate.com/test_reports

Contact support at https://codeclimate.com/help with the following debug info if error persists:
401 Client Error: Unauthorized for url: https://codeclimate.com/test_reports

Expected output:

Submitting payload to https://codeclimate.com... done!

Looks like it's currenty failing with the following:

usage: codeclimate-test-reporter [-h] [--file FILE] [--token TOKEN] [--stdout]
                                 [--debug] [--version]
codeclimate-test-reporter: error: argument --token: expected one argument

I don't know what your value of the token is so can't debug further.

This is annoying. It's not the token's fault - it's codeclimate-test-reporter, or travis not dealing with the environment variables we've setup properly. Thank you for testing this!

What I initially committed is what worked for me. See this build for details.

Thanks for flagging this, @impala2 - I've rolled your change into our travis branch and will merge that one :)
