Fix AppBreadcrumbReported bug with isolated uid

In MetricsManager::onLogEvent, we check whether the uid in
AppBreadcrumbReported is the same as the logger's uid. However, because
we map uids within LogEvents from isolated uids to host uids prior to
this, we should convert the logger uid to the host uid as well.
