Omit "version" from deposit form defaults

* missing version fields are handled by the UIJSONSerializer by
  constructing a string of the shape "v{version_index}"
* the "metadata" service component removes both the "version" and
  "publication_date" fields from new versions of records
* experience shows that users rarely put in explicit values for the
  version field, which creates inconsistency
