Core/SAI: SMART_ACTION_UPDATE_TEMPLATE and kill credit from updated entry

Description:

If original creature loses big amount of health (70% or more) and then you force it to update entry, you will not receive kill credit after killing updated creature.

I have to notice that everything works fine in this script but not in the SAI https://github.com/TrinityCore/TrinityCore/blob/3.3.5/src/server/scripts/Outland/zone_netherstorm.cpp#L336-L462 For tests: .q a 10190 .go c id 18879 damage the creature up to 70% health use the quest item kill the updated creature

Expected behaviour:

You must be awarded with kill credit even if original creature loses 99% of health.

Steps to reproduce the problem:

.q a 12516 .go c id 28068 .dam 40000 use quest item on the creature kill updated creature

Or apply #24703 .q a 10190 .go c id 18879 damage the creature up to 70% health use the quest item kill the updated creature
