Fix cucumber tests

- Updates cucumber (https://github.com/cucumber/gherkin2/issues/320#issuecomment-139572490)
- Removes `bundle exec` from commands ran in cucumber steps
- Simplifies framework_major_version (we can assume it always is 4 or
  higher)
- Inline unneeded methods
- Fix some Ruby warnings
