Fixed console purges with a radius purging all worlds (#1026)

/co purge rejects a numeric radius, but the check only saw the radius
when the sender had a location. From the console, /co purge t:30d r:50
parsed no radius and no world, so it ran as a server-wide purge. The
radius is now also parsed against a placeholder location, so it is
rejected for every sender. r:#world is unaffected.
