[Warnings] Fix actions not being taken (#2218)

When multiple warning actions were registered, and the user didn't exceed the points for the highest action on the list, no action was taken.

Resolves #2106.

Also commented out the casetype registration for warnings, since it's not actually using modlog yet.
