Clinton Wolfe 8683c54510 Update core resources with filtertable API changes (#3117)
* Search and replace filtertable methods to use new names, and rely on automatic methods
* Remove spurious exists? matchers - see https://relishapp.com/rspec/rspec-expectations/docs/built-in-matchers/exist-matcher
* Revert removing exists? - we'll do it on a separate PR
* Gah, didn't save before resolving conflict
* Add back name column on aws cloudtrail trails
