The automatic synchronization of live workspace done by this listener does not work for node with sameNameSiblings=true

For example I create 3 events node in workspace default under a "ametys:plugins" node (calendar's events of workspaces)
After auto synchronisation we have:

the 3 nodes are correctly created and synchronized

Then delete event E2
After auto synchronisation we have:

event[3] E3 becames event[2] E3 in default workspace, so for LiveWorkspaceListener event[2] E2 still exists in default and so do nothing

Add 2 events E4 and E5
After auto synchronisation we have:

when synchronizing E4 creation, node at path event[3] already exists in live workspace,
LiveWorkspaceListener does nothing
