fn_async Update for extDB v19 fetch 4:<Unique ID>

This change is not needed Altis Life can still keep using 5:<Unique ID>.
But it should reduce the majority of Altis Life get Results from 2 callExtensions -> 1 callExtension.

Note: 
SQF code needs to be tested but should be ok.
Also the required version needed for extDB would get bumped to v19.
