LP1887429 Properly handle user settings in staffcat holds
Treat user settings like the raw JSON values that they are
when fetched via fleshing. Also be sure the value for the
'opac.default_pickup_location' user setting is read as a number in the
staff catalog to ensure it can be linked to the org unit in question.
