Description

We just noticed that the functionality added in #1418 isn't working in our Rails app (which uses Rake).

The culprit appears to be this line

When running debugger:

(ruby) defined?(::Rake)
nil

However when rake is added to our Gemfile the check works.

Perhaps it would be better to execute the code without Rake?

Research direction

Start at lib/tapioca/dsl/pipeline.rb line 232 and reproduce the pending-migration check in a Rails app where Rake is only an indirect dependency. Trace why defined?(::Rake) is nil, then verify that the check works without adding Rake directly to the Gemfile.
