test(e2e): Re-enable iOS view_names assertion in captureMessage test (#6846)

The JS captureMessage event's `view_names` is set entirely in JS from the
clean React Navigation `route.name`, matching the already-enabled Android
assertion. The generated route-key hash referenced by the old TODO no longer
appears, so re-enable the assertion with the clean route name.

Closes #6844
