Trac Ticket 75 - Unconfigure plugin opperations are being called.

https://fedorahosted.org/389/ticket/75

Fix descriptions:
When plugin is not enabled, the start function is not called,
but the initialization is made and the plugins are registered.
This patch calls the initialization/plugin registration only
when the plugin is enabled.
