Fire charge plays no sound due to incorrect sound file reference

This report is a follow-up to an attempted fix for [ MC-1831 ] in version 14w31a.

I'm unsure as to whether the original issue should be re-opened or whether (as the conditions have changed) there should be a new bug report. I'll leave this up to the discretion of the mods if they wish to merge this with the original report.

[19:07:43] [Client thread/WARN]: File minecraft:sounds/mob/ghast/fireball.ogg does not exist, cannot add it to event minecraft:item.fireCharge.use

The correct asset the game should be pulling is sounds/mob/ghast/fireball4.ogg, as a result the game plays no sound for the fire charge use.

I verified that Ghasts still play fireball sounds. I verified that forcing sound assets to re-download does not resolve the issue.
