* Core/Aura: Fix SPELL_AURA_BIND_SIGHT invalid read

Mind Vision has Aura Effect SPELL_AURA_BIND_SIGHT which adds the target to a special Map container i_objectsToSwitch, used to switch grid containers for target Creatures of this Aura Effect.

When the target is a Creature, when the Creature is removed from world it's added to i_objectsToSwitch and then to i_objectsToRemove, iterated in this order in Map::RemoveAllObjectsInRemoveList() so the reference in i_objectsToSwitch is valid.
When the target is a Player, when the Player logs out it's added to i_objectsToSwitch but then Map::RemovePlayerFromMap() deletes the Player, leaving an invalid reference in i_objectsToSwitch.

Since the whole point of i_objectsToSwitch is to store Creatures and since the stored references are used only if the condition "GetTypeId() == TYPEID_UNIT" is verified, it's safe to add only objects of TYPEID_UNIT type to the container.
