When a realm owner tries to invite themselves to their own realm, the game shows the message "A player with the provided name does not exist", which is obviously not the case.

How to reproduce:

1. In your realm settings in game, go to the Players tab.
2. Click Invite player.
3. Type your own username.

Expected result:
"You cannot invite yourself to a Realm you own!"

Observed result:
"A player with the provided name does not exist"
