78648 do not call refresh_appts for OH claims

[randomsync]

Summary

For OH sites, there's no concept of "check in" currently, and so there's no concept of refresh appointments and those calls will fail if made. This PR checks the incoming parameter for facility_type = OH, and doesn't call CHIP's refresh_appointments for that case.
