sca: Fixed SCA owner on seizing a held call from a different SCA UA.

- Part of the issue reported by Kevin Scott Adams, GH #341. When using
'kamcmd sca.all_appearances' to display the appearances the owner and
the callee became the same. I think the owner should be a SCA endpoint
of the call and not a non-SCA endpoint. Uploaded compiled and tested
inbound and outbound calls.
