In org.ametys.plugins.workspaces.events.WorkspacesEventType, many code have been duplicated and should be cleaned.

One of the possibility would be to see if it is possible to add data to an event so the next observer will have access to it (and then, store the requested data in this to have the created Node itself).

Or modify the code so everything is done only once.

For now it is

• data -> node
• node -> json
• data -> json
