Claimed work type does not delete

[hueachilles]

Description

Unchecking/deleting a claimed work type on a Case with multiple work types does not go through. Unchecking/deleting unclaimed work types does.

Expected Behavior

Unchecking/deleting claimed work types behave the same as unchecking/deleting unclaimed work types. They should disappear from worker view and the status dropdown should not show in form view.
