  -----------
  Proper inheriting of branch attributes during DNS-based failover.

When creating a fake request based on an existing UAC entity, use the DST_URI and PATH_VEC specific to that UAC entity and not the per-message values.
This will correctly preserve the DST_URI and PATH_VEC during a DNS based failover, where the new branch must be a perfect copy of the original failed branch.
