Trick rspec-rails sub-builds

    ============= Starting rspec-rails specs ===============
    Bundler could not find compatible versions for gem "rspec-core":
      In Gemfile:
        rspec-core

        rspec-rails was resolved to 4.1.0.pre, which depends on
          rspec-core (= 3.11.0.pre)

    Could not find gem 'rspec-core (= 3.11.0.pre)', which is required by gem
    'rspec-rails', in any of the relevant sources:
      source at `/home/runner/work/rspec-support/rspec-core`
