Filter out members when querying using the University HR system
Filter out 'member' affiliations when querying by the University HR system.
These affiliations were filtered out in the legacy card system, so it makes sense to filter them in the card client as well https://gitlab.developers.cam.ac.uk/uis/devops/iam/card-database/card-system/blob/master/applications/plsql/univcard/DAILY.PKB#L848.
This reduces the number of additional people seen in card client exports when querying using the University HR system.
