Exception thrown when calling #alive

Using the example in the README, with netrc configuration:

/Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:39:in `[]': no implicit conversion of Symbol into Integer (TypeError)
	from /Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:39:in `set_access_token_from_params'
	from /Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:32:in `block in authenticate'
	from /Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:17:in `without_authentication'
	from /Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:29:in `authenticate'
	from /Users/xavier/.gem/ruby/2.3.1/gems/looker-sdk-0.0.5/lib/looker-sdk/authentication.rb:10:in `ensure_logged_in'

	from test.rb:9:in `<main>'

This seems weird because:

• Documentation claims it's not even trying to authenticate, but stack trace looks like it is.
• I know my supplied credentials are invalid, I'd expect an error message that suggests as much, rather than the inscrutable no implicit conversion error.

I agree that the code doesn't do what the comments claim. It hasn't for a long time. I think that expectation got broken very early on when the sdk was changed to automatically manage its authentication. I'll make a PR with a fix.

The exact error condition there surprises me. The implication is that the server returned a 200 OK for the /login request but, the result body was not of the form expected. I would not expect that of a real Looker instance.

Thank you! Our looker is behind an in-house proxy authentication service, so possible that's contributing to the weirdness you noticed.
