Bug 30714: Do no log update to holdingbranch

When an item from another branch is checked in, the holdingbranch is
updated, and this change is logged.  We record the checkin in
statistics, we do not need the cataloguing update logged

To recreate:
1 - Enable cataloguing log
2 - Check in an item with a different holding branch
3 - Check the action logs
4 - There is a cataloguing log for the holdingbranch update
5 - Apply patch
6 - Repeate with another item
7 - No log added!
