dimi b98b77568d Bug 1346196 - URLCLASSIFIER_UPDATE_REMOTE_STATUS2 records values using empty keys. r=francois
mTelemetryProvider might be empty if |CancelUpdate| is called during update.
In that scenario, the call flow will look like:
CancelUpdate -> UpdateError -> DownloadDone -> set mTelemetryProvider to empty ->
OnStartRequest -> record telemetry with empty key.

So in this patch, move mTelemetryProvider.Truncate() to OnStopRequest.
