When generating uri-ref data, use different logic that what is used for uri generation

[tedcasey]

Expected Behaviour

Nodes marked with uri-ref format should have data generated for them that more closely mirrors the intent behind the spec - i.e. fragments, relative urls, etc, as opposed to what's required for a uri (fully qualified uri).

Actual Behaviour

Nodes marked with uri-ref get fully qualified URIs generated for them.

Reproduce Scenario (including but not limited to)

Schemas with uri-ref nodes

Steps to Reproduce

Generate a Model object instance that consumes a schema with at least one node that has a uri-ref format indicated.

Note how the generated data is a fully-qualified uri.
