worker: fix nested uncaught exception handling

We are using `ObjectPrototypeToString()` as a cross-context brand check
for built-in errors, but weren’t making sure to set that when
deserializing errors back into JS objects.

Fix that by setting `[Symbol.toStringTag]` manually, to make sure that
multiple serialize-and-deserialize cycles keep giving the same result.
