LPS-48206

Hey Julio,

This solution affects only to actions (EditGroupAction, EditUserGroupAction, EditOrganizationAction, EditUserAction) so we cannot provide a test for it. 

The LayoutSetPrototypePropagationTest already uses the same mechanism to ensure the propagation of changes programmatically through the invocation of the LayoutLocalServiceUtil.getLayouts(L, B, L) method. 

I've added a comment to explain what this code is for.

Thanks
