Errors from before sourcemaps were uploaded

Looks like the new issues for that release have a stack trace showing, but it’s wrong: https://sentry.io/organizations/ginger-labs-inc/issues/1181881051/?project=1393587&query=is%3Aunresolved&statsPeriod=14d

It’s the same issue I mentioned here: Stack traces are inconsistent and sometimes wrong

We are using the new RN Sentry beta (version 1.0.0-beta.6).
