Disabling a relationship type used in a case role causes the label to be blank on the case type edit screen
I know there's differing opinions on what a disabled option value means but probably everyone would agree that a blank row seems wrong. Interestingly everything still seems to work and it lets you save. And when you view an existing case it still shows the previously assigned role correctly (in my opinion). But where this came up was while working on #1046 (closed) I'm noticing that the existing functions only return active option values, and that's fine sometimes but that isn't what you want when converting values/names to labels or doing comparisons against name, which is also what's happening here. TBD.
