Use urlparse to compare interactivetoolsproxy_map with `database_…

…connection` and `install_database_connection`

Using `urlparse` rather than `sqlalchemy.engine.make_url` decreases the precision of the comparison, but removes the need to declare `sqlalchemy` as a dependency of the config package.

This is a tradeoff between convenience (preventing mistakes from the user) and complexity (number of dependencies of the config package).
