fix(records): show a deleted practitioner on the live visits that name it

The web record and the doctor report named the practitioner of a live
visit after the address-book entry was deleted; the MCP read, the search
and the appointment reminder did not. All of them now name it, the entry
stays out of the address book and the pickers, and a portable backup
carries it as a tombstone instead of dropping the visit's reference.
