Rails' binstubs vs. Bundler binstubs

There's an incompatibility in the Rails vs Bundler-generated bin/bundle binstub. Futher, other Bundler-generated binstubs (e.g., bin/rspec) generated by older versions of Bundler don't play well with those generated by Bundler v1.16.

The Binstubs and versions.

bin/rspec

The older rspec-old.rb was generated by an older version of Bundler.

Heroku Release Phase + Review Apps + Rails

This is a simplified, but fairly thorough, set of scripts and configuration to enable Heroku Release Phase for Rails apps. Further, this particular set up plays nicely with Heroku Review Apps in that the release phase script will:

1. Fail, loudly, if the DB does not yet exist.
2. Load the DB schema if the current schema version (as determined by bin/rails db:version) is 0.
3. Run DB migrations otherwise.

For a "normal" app that usually means it will run the DB migrations.
