Fix up tags attribute in revisions API

Currently the GET /revisions endpoint returns the tags associated
with each revision like:

    tags:
      foo:
        name: foo

Which is strange, because the name of the tag is recursively referenced
also as `name: foo`. Thus, this PS re-formats this response body to
be more sensible:

    tags:
      foo: {}

Where the key is the name of the tag and the value is the data, if any,
associated with the tag. If no data is associated, the dict is empty.

This PS also makes necessary documentation and functional test updates.
