Mob hurt/death sounds overlap each other when manually spawned & killed.

Update by [Mojang] Mega_Spud (Jay Wells):
Steps to Reproduce (example):

• Use the command /effect @p strength 400 40
• Spawn a Ghast
• Hit Ghast, notice the hurt and death sound play together

In the Java version, just the death sound is played, not the hurt sound as well.

Original Description:
When killing any mob, their 'hurt' sound plays along with their 'death' sound, as opposed to ONLY playing the 'death' sound.
