Attaching a Cartridge Isn't Always Adding the Associated ENV Vars

[vindir]

When creating a test app, the mysql cartridge was added, but when dumping expected environment variables in the sinatra app.rb they are not being populated.

This is likely related to the caching issue seen with cartridges already, but needs to be tracked down.

Test app: http://trysinatra1-jho.apps.mojolingo.net/

We would expect OPENSHIFT_MYSQL_DB_HOST, OPENSHIFT_MYSQL_DB_PORT, OPENSHIFT_MYSQL_DB_USERNAME, and OPENSHIFT_MYSQL_DB_PASSWORD to be populated with valid values.
