Only count other users' Places for the Edited leaderboards#69

The current leaderboards for “Places Edited”, both on Destination Guides and user profiles, count the same user’s Places.

This means that if someone wants to increase their count, they can do so by editing their own Places. My own example with Outer Hebrides: https://www.atlasobscura.com/things-to-do/outer-hebrides-scotland

Probably 10 out of my Edited are the ones I added myself, many of which were published with small typos I corrected, so I think it’s preferable to NOT include our own in the count.
