It's necessary for a delegate's references to be present, e.g.
verification, calculating of canonical data, etc.
To ensure that a user does not get themselves into a state where they
have added a delegate without their references, prevent adding a
delegate to the identity document if their `rad/sigrefs` is not
present.
As well as this, it ensures that if there is a `rad/sigrefs` that it
has the default branch -- since it's possible for a peer to have created
`rad/sigrefs` through COBs without a default branch.
This change meant that the `rad-id` tests required the test scenarios
to be set up with all nodes having each other's references. A test
case to add a missing delegate was also added to `rad-id.md`.
