n-api: refactor a previous commit

Octavian Soldea · targos · commit e6b3bfe1118c · 2019-08-02T22:23:57.000+02:00
This is a refactoring of #27628 following #28505. This change factors out functions `add_last_status()` and `add_returned_status()` so they may be reused in the tests for passing information about the last error status and/or a returned `napi_status` to JavaScript. PR-URL: #28848 Reviewed-By: Anna Henningsen <anna@addaleax.net> Reviewed-By: Gabriel Schulhof <gabriel.schulhof@intel.com>
