Persist the correct Gemfile to each test app (#5790)

With this, we no longer need to mess with `BUNDLE_GEMFILE`'s when
booting applications for different Rails versions, and each application
will always use the right Gemfile. We can even boot applications from
the root folder like this: `tmp/rails/rails-6.0.0.rc1/bin/rails s` and
it will just work.
