Document.createdOn is always identical to lastModifiedOn and updated on every save

[pcdavid]

In org.eclipse.sirius.web.domain.boundedcontexts.semanticdata.Document the createdOn and lastModifiedOn are always the same, and do not correspond to "the time when the user created the document" and "the last time when the content (or name) of the document has been modified".

In practice they are always identical both correspond to the last time the SemanticData was saved, regardless of any actual change (and then technically not really, because boths the Document instances and the SemanticData instace will be created at possibly a few microseconds of difference).
