Bug 33792: reserves_stats: Undo homebranch and holdingbranch preselect

This preselect cuts off all next available holds that are in reserves,
as well as holds filled by checkout without confirm (see 33791).

Test plan:
Go to reporting. Click Hold statistics.
Verify that Holding library and Home library are not selected.
Test that you can still filter by one of those.
