[MC-152585] playerdata XpTotal does not update itself when changing Xp with "/xp set"

The Bug:

The value of the XpTotal tag does not update itself when changing Xp (no matter if level or points) with the command "/xp set ...". It can only be changed by the command "/xp add ..."

Score is affected in the same way as XpTotal.

The command "/xp query ..." is not affected.

How to reproduce:

Add 5 xp
```
/xp add @s 5
```

Set xp to 0
```
/xp set @s 0
```

Check XpTotal

/data get entity @s XpTotal

--> "@s has the following entity data: 5

Does MC-118008 describe your issue?

Yes partly, it seems to be related to my problem. But with MC-118008 there is no indication that the change by "/xp set @s 1 points" does not change XpTotal either. There the focus is on the change by "/xp add @s 1 level". I don't know if that has the same cause.
