Every time the user changes the priority of the content, the sub-items list is refreshed (unlike the Content Tree).

Steps to reproduce:
1. Create few content objects (more than 1) in any subtree e.g. Home.
2. Visit the "Details" tab of Home content.
3. Change default sorting in "Sub-items sorting order" to "Location priority" in "Descending".
4. Change the priority of any item in the sub-items view of Home.

Result:
The sub-items list is refreshed every time priority is changed, but the default sorting is still preserved in the Content Tree.
