Problem description: checkboxes in the lists of hosts, templates and items are not cleared after mass update gets executed. Such behavior degrades the usability in case if the user modified entries on multiple pages of the corresponding views, as he'll be forced to go through all pages with selected entries to deselect them.

Steps to reproduce:

1. Navigate to Configuration => Templates, Configuration => Hosts or Configuration => Hosts/Templates => Items
2. Select a couple of entries from the host/template/item lists
3. Press mass update button
4. Update any of the fields in the massupdate view
5. Press update button

Result: the checkboxes next to the entries that were selected for the mass update are still checked.
Expected: because the mass update action already took place the checkboxes should be unset.
