Running everything in `bundled_app` by default causes the `bundled_app`
helper to be used everytime, and that will create a scoped bundled_app
folder if it does not exist. That causes `bin/rake spec:deps` to create
an empty `tmp/2.1/bundled_app` folder which is a bit weird.
This commit changes specs to not switch to a (possibly empty)
bundled_app directory when not necessary (for example, when running
`gem` commands in order to setup test dependencies).

When launching bundler subprocesses for end to end testing, all of them
will load the `spec/support/rubygems_version_manager.rb` file passed as
a ruby's `-r` flag.
Unfortunately this file depends on `pathname`, so unless we drop that
dependency, we can't really test support for including the `pathname`
gem in the `Gemfile`.
This commit implements some refactorings to avoid loading `pathname`
inside `bundler` test subprocesses.
