[8603] corrected comment of last commit

the problem was in Unit::setFeared
which got called after removing a fearaura

inside setFeared there is a check for isAlive()
which will return true in this case, cause m_deathState
is updated only after RemoveAllAurasOnDeath()

a fix could be to set m_deathState earlier, but
then auras which require a spellcast on remove
won't work anymore..
(not sure if we actualy have such auras)

but if in future more functions will require special code there,
moving the m_deathState setting should be considered

big thx to Naicisum for explanation and investigation
