Log Message:
Update ruby-rspec-expectations to 3.6.0.

### 3.6.0 / 2017-05-04
[Full \ 
Changelog](http://github.com/rspec/rspec-expectations/compare/v3.6.0.beta2...v3.6.0)

Enhancements:

* Treat NoMethodError as a failure for comparison matchers. (Jon Rowe, #972)
* Allow for scoped aliased and negated matchers--just call
  `alias_matcher` or `define_negated_matcher` from within an example
  group. (Markus Reiter, #974)
* Improve failure message of `change` matcher with block and `satisfy` matcher
  by including the block snippet instead of just describing it as `result` or
  `block` when Ripper is available. (Yuji Nakayama, #987)

Bug Fixes:

* Fix `yield_with_args` and `yield_successive_args` matchers so that
  they compare expected to actual args at the time the args are yielded
  instead of at the end, in case the method that is yielding mutates the
  arguments after yielding. (Alyssa Ross, #965)
