CKAN Version if known (or site URL)

2.5.2

Please describe the expected behaviour

On group page, eg http://demo.ckan.org/group the pagination links at the foot of the page should preserve the sort order

Please describe the actual behaviour

The sort order is set to the default

What steps can be taken to reproduce the issue?

Create 22 groups (currently available at http://demo.ckan.org/group)
Go to the group page
Change the sort order to "Name Descending"
Go to page 2

The group on page 2 should be the first alphabetically - instead it's the last

This has already been fixed for organizations - see #2141 and #2153
