Error thrown inside an async rule are not sent to the fallbackError function

Describe the bug

If an async rule throws inside a chain, the error is not sent to the fallbackError function. The value is null.

Example

const editorIsEventOwner= chain(
  isPromoterStaff,
  rule({ cache: PermissionCache.STRICT })(
    async (_parent: {}, args: { id: string }, ctx: Context) => {
      const { id } = args;
      const event = await findEvent(toInt(id), ctx); // This can throw an Error
      if (!event) return false;
      return event.ownerId === ctx.user?.id;
    }
  )
);

This will correctly not allow the user to proceed if the findEvent fails, but it will not put the Error in the first parameter of the the function.

I created a wrapper for the rule function. I would be willing to rewrite part of the lib to support more native feature if @maticzav let me. I basically did it with nexus-shield. I think the shift to throw would be better.
