ha: Sync remote address in HA_IKE_ADD, too

When the IKE_SA is synced without the remote address, after a
reauthentication charon is not able to find it in its connected_peers
table since the destination host will be %any (it's missing in the
message, hence the default from the newly created ike_sa_t -- %any --
will be used).
By adding the value to the HA_IKE_ADD message, we should be able to
solve this problem.
