Title: Improves exceptions logging

While using [ui/django-rq](https://github.com/ui/django-rq) and `django.utils.log.AdminEmailHandler`, I faced two issues:

- `UnpickleError` weren't caught, and therefore I didn't get any mail when incorrect arguments were passed to RQ;
- Mails were poorly formatted.

At first I thought it was coming from django-rq, but after digging I realized this was comming from RQ. This pull request fixes these two issues.
