fix crash when a cardmenu becomes an orphan (#4682)
* fix crash when a cardmenu becomes an orphan

when a cardmenu is closed the cursor on that card reverts to the open
hand, this crashed the client when that card would be destroyed or moved
the act of reverting to the open hand now happens as an emitted signal,
this way it just doesn't exist anymore when the card is deleted.

* simplify fix
