We currently track a video upload and thumbnail upload together, and call handleUploadFailure once when either of them fail. We should mark them both as failed, so the thumbnail doesn't appear to be "in progress" from the perspective of InputState.uploadInProgress.
This fixes report upload on video message retry, which was previously broken because the thumbnail would appear as in progress to InputState.uploadInProgress, which is checked in canSendReports.
I considered teasing apart the thumbnail upload so it could tracked on its own, and wouldn't need to be retried if the main upload fails. However this looked to be a more significant investment than I have the time to focus on right now.
