Subject: [PATCH 1/2] Fix incorrect expectations on getReferenceKey without and
 right type specifier

These should be false, as `link.other.getReferenceKey()` should return a key for `Patient/p3`. The absence of the type specifier should not cause this to return an empty collection, rather the collection should be unconstrained by the type of the reference.

In the case where it is the right type specifier, it should also return a non-empty collection.

Subject: [PATCH 2/2] Remove implementation-specific field from reference key
 test

The inclusion of the direct result of the getReferenceKey call in the test makes it implementation-specific and moves outside of the scope of the specification.
