Fix LightKeeper tasks not progressing correctly (!91)

To handle in-raid LK task unlocking, when a task is switched from AvailableAfter to Locked, instead switch it to AvailableForStart

This handles the lack of `status` values for tasks, where the target state would normally be read from, without risking breaking non-LK tasks by adding that data.
