Keep self and context out of error notification payload.

Back in the day, having self and context in the error notifications
was handy for debugging. Now, there is a lot of confidential stuff
stored in these objects (especially when self = ComputeManager) ...
like passwords, etc.

This patch strips it out.

Also removes dead wrap_exception calls (which did nothing since they
did not specify a notifier).
