Time Played metrics don't recognise that the player has left

[Maelstromeous]

We should probably hold a Last Seen on the InstanceCharacterAggregatate which shows the last time the person was seen, the accout the XPM metrics based off that rather than first time seen.

I actually only played this alert for about 20 minutes, Time played is going off first seen not last seen.
