Bug description

Apparently, I have 2 players with the same recorded username but different UUIDs. My best guess is, player 1 had this username first, and changed their username, but never logged back into our server, so the name didn't update. Then, player 2 picked up that username when it became available, but essentials still has the username recorded for player 1, so when I do /seen on the username, it's showing me player 1 when I'm actually trying to /seen player 2. Is there any way for Essentials to maybe recognize there are 2 user data files with the same username recorded, and give the option to choose which one you want to view when using /seen? (I was just reminded of when there's multiple /recipes for the same block/item, you can choose which recipe to view)

Steps to reproduce

1. Update to the latest dev build of EssentialsX
2. /seen username

Expected behaviour

I expected to see the /seen info for player2

Actual behaviour

It showed the /seen info for player1, same username, different UUID
