[11670] Implement in proper way ITEM_SPELLTRIGGER_ON_STORE (5)

Browse source 
Item spells with this trigger mode expected casted at item add
to inventory/equip slots (exclude bank), and spell auras (if any)
applied while item in like slots. Item expected destroyed at aura
remove by some reason.

Implementation note: because 2 step way item moves from slot to slot
related auras not removed at internal RemoveItem call and removed only
at directly item destroy/remove from player function calles, or at StoreItem
(if item added to not appropriate slot). So need in future careful with new
RemoveItem call cases.
