AppGenerator: Replace 'rake' with 'rails_command'

Since Rails 5.0 is switching the Rails command line from 'rake …'
to 'rails …', it makes sense to also replace the `rake` method in
the Rails templates API.

Based on feedback from @matthewd and @kaspth, I chose to replace
`rake` with `rails_command`, which is less confusing than
the alternatives `rails` or `command` or `rails_run` and is not
Thor-reserved word like `task`.
