Title: Allow RSpec's rake task to live with MiniTest

Rails apps can't have both `rspec-rails` and `minitest-rails` loaded at the same time. The Rake task is loading `rspec/core` which loads the DSL which stomps on MiniTest's spec DSL.

There will be an accompanying pull request for `rspec-rails` that is also needed. Here is a [gist](https://gist.github.com/cd39c4bbd5f710df696b) that shows these changes working in a test Rails app.
