**I have following issue:**

Tried calling `Sentry.lastEventId()` on the main screen of our app after a crash had happened and it returned `undefined`.
Looks like event Id is not persisted?

**Steps to reproduce:**

* Call `nativeCrash()` from "@sentry/react-native"
* On app relaunch call `Sentry.lastEventId()` and inspect value returned.

**Actual result:**

`undefined`

**Expected result:**

Some sort of Id

Commencez par l’API Sentry.lastEventId() et le chemin de reproduction de nativeCrash() dans @sentry/react-native ; le payload n’indique ni fichier source ni test. Reproduisez le crash, relancez l’application iOS et examinez la manière dont l’ID de l’événement est géré au franchissement de cette limite. C’est terminé lorsqu’un ID d’événement de crash est disponible via Sentry.crashedLastRunEventId() après la relance.
