BUG - /groups/{}/permissions offset is always zero

[rtisma]

From Ego swagger, /swagger-ui.html#/Groups/getGroupPermissionsForGroupUsingGET, say there is only 1 permission for a group, when you set offset=10000 and limit=100, a page is returned with a non-empty result set. The result set should be zero

This is blocking the DMS from provisioning permissions.
