/tpno does not work

"/civilization:tpno" tab completes, so I think this command is meant to work (most likely as an alias to /tpdeny), but currently "/tpno" triggers Essentials TPA (message "Error: You do not have a pending request."), meaning it doesn't work to actually deny a TP request. Not sure if this is an issue with Essentials commands not being disabled, or the Civilization factions plugin itself. Reporting as Minor as this is likely a rarely used alias
