Creakings not linked to any heart display wrong subtitles when attacked with non-damaging projectiles

When attacking a creaking that has been summoned via a spawn egg or commands, and not through use of the creaking heart, with non-damaging projectiles, such as snowballs and eggs, the subtitles will erroneously display "Creaking is shielded" instead of "Creaking hurts", causing inconsistency with other mobs.
