Banner skill doesn't auto-swap weapon sets

Defect: Banner skills (War, Defiance, Dread) does not trigger an auto weapon swap even if they are allocated to a specific weapon set in the skill page.

Expected behavior: Using a banner skill tied to a weapon set group changes the weapon set.
Current behavior: Banner skills are greyed out and does not trigger the weapon set.

How to reproduce:
* Apply Banner skill to weapon set 1 only by deactivating weapon set 2 on the skill page.
* Apply another skill (e.g. warcry) to weapon set 2 and deactivate weapon set 1 on the skill page.
* Trigger the weapon set 2 skill by using the skill(e.g. warcry). Validate that the weapon has been swapped.
* Use the Banner skill to force sawp to weapon set 1.
