Add multidb application test

I realized I wasn't really testing some of the new rake tasks added so I
built out this new test that uses a multi-db database.yml and allows us
to run create/drop/migrate/schema:dump/schema:load and those that are
namespaced like create:animals. This will make our testing more robust
so we can catch problems quicker and set a good place to add future
tests as these features evolve.
