Description
The tab complete for the xp command is a bit messed up. When doing /xp give/set/take it won't suggest a player but will suggest adding l after you type a number, and then will suggest names after you press space. /xp reset also doesn't suggest anything at all.

Steps to reproduce
Type /xp give (or set / take)
Type a number and it'll suggest adding l
Press space
It suggests names

Type /xp reset
It suggests nothing

Expected behavior
/xp give/set/take should have the tab suggestions flipped as you have to type the username first and then the amount of xp

/xp reset should act like /xp show where it suggests a name to use

Needs investigating, but this sounds like the tabcomplete for the command wasn't updated when its syntax was updated.

I can confirm that the XP command has a broken tab-complete.
