The stun agent may contain references to the password previously stored
in some remote candidates, freeed by nice_component_restart(), that were
used by keep-alive stun requests. These stun replies may arrive later
after ice has been restarted. Since the remote candidates are freeed
when ice is restarted, the stun agent must be reset to get rid of these
related references.
