Added a negative test to ensure the RFC Editor is not included on notifications of manual posts by the Secretariat unless the document is in the RFC Editor Queue.
Also added a directory for staging of manually submitted drafts, instead of using hardcoded /tmp/, and added creation and removal of a test directory for this.
