LP1277556 Fast Item Add no longer opens record after copy is created

Altered save_attempt to handle undefined and true cases for replace_on_complete
When fastItemAdd is not used, replace_on_complete is undefined
When it is used, and successful, replace_on_complete will be set to true
then we need it to execute result.on_complete()
