- fixes tag creation when creating posts with `tags: [{slug: 'new'}]` which should be supported
- assigning tags with only `{slug: 'new'}` was triggering our validation for the required `name` property then bubbling up to the `bookshelf-relations` library resulting in a 500 error
- the fix applied here is to set the `name` field to the same as the `slug` field if a name is not provided

The transaction no longer commits in the promise chain, which wasn't
valid logic for a transaction, since it is commited automatically when
the promise chain resolves, and rollsback automatically when the
promise chain rejects.
This makes code which fails during the transaction error in the right
place, instead of getting stuck here. (Especially good for writing
tests).
The tests for this code can now live in the integration folder.
