bitbake: event: remove mapping for deleted event handlers

The current remove method for class event handlers does not update the
event mapping after an event handler is deleted from the main dictionary.

This change enhances the remove method by also updating the event mapping
accordingly.

This was detected after creating the bb.tests.event module.
