addAttackingCreature must have protection from double calls (throw error)

Potentially same double call bugs (duplicated combat group and damage), see #13452

But it also has potentially buggy code while declare attacking player who have a planeswalker — looks like it allow to choose planeswalker anyway, but it must be restricted (?). Need research. Potential bugs: reports that AI can target player and planeswalker with same creature. Also need research [[Capricopian]]. Also make sure it’s impossible to call already attacking permanent (if it does then make sure it remove from combat first like Capricopian do).
