// we always fix this issue because there does not seem to be a good way to prevent it.
// Scenario in which this can happen:
// 1. user on instance A deletes the note (sync for notes is created, but not for note_contents) and is later erased
// 2. instance B gets synced from instance A, note is updated because of sync row for notes,
// but note_contents is not because erasion does not create sync rows
// 3. therefore note.isErased = true, but note_contents.content remains not updated and not erased.
//
// Considered solutions:
// - don't sync erased notes - this might prevent syncing also of the isDeleted flag and note would continue
// to exist on the other instance
// - create sync rows for erased event - this would be a problem for undeletion since erasion might happen
// on one instance after undelete and thus would win even though there's no user action behind it
//
// So instead we just fix such cases afterwards here.
