Warnings from Ruby 2.4

[caboteria]

We switched to Ruby 2.4 and now we're getting many warnings. They mostly fall into two categories: /usr/local/bundle/gems/capybara-angular-0.2.6/lib/capybara/angular/dsl.rb:13: warning: instance variable @ignoring_angular not initialized and /usr/local/bundle/gems/capybara-angular-0.2.6/lib/capybara/angular.rb:10: warning: instance variable @default_max_wait_time not initialized They appear to be harmless but they happen often enough that it makes it hard to find legit log messages.
