Suppress retry with Http code 422 during Upload

Changes:
* error code 422 (Unprocessable Entity) is returned by the
  REST API when the table the bulk import session was created
  against has been deleted. The bulk import session has become
  *invalid*: any further attempt to upload, perform, or commit
  is refused
* the bulk import session can be deleted when the table has
  been deleted
