Avatar stats don't update after another user uses a buffing abililty

[CuriousMagpie]

Description

The web's party interface doesn't show people's updated health/exp/mana on mouseover, say after you've used a MP sharing ability (and hit sync), or been away for a while. Moreover, clicking on a person's portrait, or clicking on "view party", show the right amounts, but mousing over even after doing that still shows the old ones. It appears there's not really any way to update those values besides closing/reopening. Hitting Sync also doesn't affect it.

Quick check, does this issue persist even after you cleared cache?
Once cache and cookies are cleared, the values should be updated on mouseover.

Hey, I'd like to try and tackle this if that is ok.
This is potentially my first contribution ever, so if there is something I am doing wrong please don't hesitate to correct me.

I believe the problem was introduced in #14544, because the state is no longer being updated in the cast method of bulk spells.

My proposed change is by updating the state after the action user:castSpell is called in the castEnd() method in website\client\src\mixins\spells.js.
