[BUG] Merc AI breaks when they have access to "you can apply an additional curse"

"As the title said. While the interaction does work mechanically and the mercs can apply the extra curses, their AI does not account for the possibility. Mercs will actively avoid trying to apply a curse on an enemy that already has a different curse, even if they have sufficient maximum curse for both to be active.

This is less noticable with curse on hit gear since that will be applied naturally as the merc attacks, however, they will completely stop using any in-kit curses, even going as far as to avoid applying them with bane. The only way to get the extra curse is for the merc to randomly use that ability first before any other curse is applied.

In practice, this means that curses that mercs can naturally use are basically never applied, which is at best a ridiculous interaction and more likely a bug."
