/**
 * This file adds a 'guardedCatch' function to the Promise API. This function
 * has to be used when we don't want to swallow real errors (crashes), like
 * 'catch' does (i.e. basically all the time in Odoo). We only execute the
 * 'onRejected' handler if the rejection's reason is not an Error, and we always
 * return a rejected Promise to let the rejection bubble up (and trigger the
 * 'unhandledrejection' event).
