fix(destroyable): take template factions from factionList, keeping -1

The client reads an object's factions only from the DestructibleComponent
factionList (LWODestroyableComponent::LoadDataFromTemplate 0x00c9f900: one
atol per comma-separated token, -1 kept; the faction column is not read),
and live replicated that list: [-1] on 12,829 constructions (vendors,
quickbuilds, bouncers). DLU added the faction column and dropped -1,
so those objects were sent with no factions, and the four rows with faction 6
but factionList "-1" were sent as [6].

-1 has no Factions row, so it adds no friends or enemies.

Test: ReplicaConstructionTest.TemplateFactionMinusOneIsReplicated.

Check in game: vendors, quickbuilds, bouncers and NPCs still can't be
attacked; enemies still fight players and pets; smashables still smash.
