Subject: [PATCH] Made sure all $ref objects contain only a $ref property

The IETF JSON Reference spec, section 3 (syntax) says the following:

    Any members other than "$ref" in a JSON Reference object SHALL be
    ignored.

We have two groups of tests that have a $ref at the root level of the
schema, referring to a definition that is also at the root
level. According to the spec, a $ref object should not have any sibling
properties.

To make those JSON references valid, I've refactored those test cases to
use a $ref object as a json schema property definition instead, which
is valid.
