[storage] relies on event=='deleted' to detect "delete" event (closes #2450680)
When we delete a previously edited entity, it *will* have a cw_edited attribute
even if the goal is to delete it. The function get an argument that explicitly
contains the "delete" event. The code now uses that instead.
[composite] apply composite on new enty too
Before this changesets, automatic deletion did not applied to entity created in
the same transaction. This patch remove this filtering in the dedicated
operation.
The original filtering where introduced by 5d889b4928bb but no rational where
found for this changes.
The former behavior is seen as inconsistent and creates bug in some cubes.
