Subject: REST: Allow update of bundle without patches

Presently, when updating a patch we assume that patches are provided.
This isn't necessary - you might just want to make it public - and isn't
enforced by the API itself. However, because we make this assumption, we
see a HTTP 500. Resolve the issue and add tests to prevent a regression.

Resolves: #357
