Bug 25008: Regression tests

This patch highlights a behaviour of Koha::RecordProcessor that is
unexpected: if you change the original options using ->options, the
loaded filters don't pick the change. That's because the filter objects
are loaded on ->new, and they are never updated.

To test:
1. Apply this patch
2. Run:
   $ kshell
  k$ prove t/RecordProcessor.t
=> FAIL: Test prove ->options doesn't update the filters!
