Fixes possible issue with no-op creator.
Leaving a no-op CREATOR can lead to issues. We throw a run-time
exception to prevent anyone from using this. The StatsLogEventWrapper is
meant to be write-only since it's only used to send data to statsd.
Bug: 112550251
Test: Tested with provided POC app by external researcher.
