Stacktrace

Description
Just a simple permissions check, originating from the TAB plugin (which, I might add, is a terrific plugin).

The calling stacktrace is off by a couple of lines due to other commits, but the calling code hasn't changed. It's just a bungeecord-specific player.hasPermission("tab.staff") check:

https://github.com/NEZNAMY/TAB/blob/master/src/me/neznamy/tab/shared/ITabPlayer.java#L125

https://github.com/NEZNAMY/TAB/blob/master/src/me/neznamy/tab/platforms/bungee/TabPlayer.java#L48

I'm not sure why this error occurred. It seems like a normal permissions check. I know that TAB runs almost entirely asynchronously, but LuckPerms claims to support full concurrent API usage.

Lets add this one too, same thing.
