fix(resolver): remove LinkElement hook main dereference

LinkElement visit hook works on top of ApiDOM only,
and has no effect when serialized into POJO.
This commit disables this visit hook.

LinkElement is a runtime things, we're not making
the LinkElement.operationRef absolute as during the runtime
relative references might resolve against different
URIs then in parsing/dereference phase.
