Applications may not have a primary configuration so we should not assume there is one. In both these cases we can get the right connection without that. For the databases.rake file we want to re-establish a connection for the environment we're in. The first config defined under an environment for a multi-db app will win. This is already the case on application boot so we should be consistent. For the info.rb file we already have a connection so we can lookup the adapter from the connection's db_config. If a primary hadn't existed this would have thrown an exception. Followup to https://github.com/rails/rails/pull/39535 which removed the assumption there was a primary config from the schema cache load railtie.
