Title: require bundler groups to include rake-tasks in engines

If you generate a full engine, this will include rake tasks from
your gem under the `app` namespace. For example if you have a dependency
on `rspec-rails` in your engine's `gemspec`. You will get the task `app:spec`

This is a fix for #8229

Trailing whitespace snuck into the CHANGELOG. I removed it in a separate commit to make backporting easier.
