Description

Steps to reproduce:
1. Create List with custom itemRenderer and set data provider with some objects to it;
2. Reset List's dataProvider to empty one;
3. Change List's itemRenderer to a new one;
4. Reset List's dataProvider to one with some objects in it;

Actual Results:
itemRenderers from step #1 is used instead of itemRenderers from step #3

Expected Results:
itemRenderers from step #3 should be used

Workaround (if any):
1. Extend List, import and use mx_internal namespace;
2. Override itemRenderer setter and set up boolean flag in it along with setting super.itemRenderer;
3. In commitProperties method before calling super.commitProperties() check for boolean flag and dataGroup and if check is passed call dataGroup.clearFreeRenderers()
