Changing patron group for one user doesn't change filter result count when result count is more than 1,000

Overview: Bugfest test https://foliotest.testrail.io/index.php?/tests/view/15999&group_by=tests:id&group_order=asc&group_id=-1 describes changing a user's patron group and then checking to be sure the patron group count in both the old group and the new group reflect the change.

Steps to Reproduce:
#1 Login into the bugfest-goldenrod environment and make note of the patron totals in two groups
#2 Edit a patron's record from one group to another and save
#3 Note that the data is saved correctly in the UI

Expected Results:
the count of the patrons in the first group should be one less, and the one the patron was changed to should be one more.
Actual Results:
The counts in the groups stay the same

Additional Information:
There used to be a correspotnding number of users in the Settings>Users>Patron groups table the would also reflect the numbers of patrons, but this table no longer works and the "# of users" is always 0. CB: This is a separate issue which has been addressed, with SME permission, by simply removing the broken column. UIU-1562
