Keep UploadFinished Paired with UploadStarted When an Upload Throws

The exception from a throwing upload was caught around perform_job, so the UploadFinished lifecycle event was skipped and plugins saw an upload start that never finished. The catch now sits around the upload call. The error is reported through the job's error callback and UploadFinished is fired with an error code, as for any other failed upload. The worker keeps running for the next job. The started, upload and finished sequence moved to PrintHostJobQueue::upload_job so it can be tested without the dialog.
