Only create test databases when Rails.env.test?

Previously, running rake db:create with either no
RAILS_ENV or RAILS_ENV=development also created
the test database(s).

A typical DM app will probably have some sort of
auto_migrate! or auto_upgrade! call in spec_helper
anyway, so this seems redundant
