NascentUpload.do_reject can send an Accepted email

NascentUpload.do_reject sends an Accepted email if the upload made it to Done before an exception occurred (eg. because build creation failed). The transaction is still aborted, so the email is a lie, but it is concerning.

The problem is that it attempts to call setRejected, but ignores any exception (usually a QueueInconsistentStateError because Done -> Rejected is invalid). It then calls notify without overriding the status argument.
