rake initialize is not idempotent #21
Description
Rake initialize works great for a freshly generated app, but it will fail (with an assortment of errors) in a number of other circumstances. For example:
• Someone else generated the app, pushed it to a repo, and you just pulled it. (so e.g. secrets.yml.example exists but secrets.yml does not)
• You are starting up a new clone of a project you've worked on before, so a database by that name already exists.
Maybe not a critical issue (particularly the second one), but worth noting.
