hal_json_style: adjust transaction interactions in the test

 - the transaction is aborted in tearDown, no need to abort
  explicitly, for same reason if we want to delete documents, we
  need to explicitly commit (see TestERP5Person_getHateoas_mode_search)
 - simulate decorator should not commit the transaction to keep this
  semantic of abort by default, which keeps test isolated.
