This commit gets the Travis build passing by:
- Removing Rails 4.2 so we don't have to deal with bundler < 2 anymore
- Bumping to latest Rails versions
- Explicitly listing all gems that appear in the default Rails Gemfile
- Avoiding bootsnap and javascript, since they aren't relevant to these tests

template.
