Bug: uib-uncheckable not working on radio button directive

[JAnderson1122]

I found this using your demo page: https://angular-ui.github.io/bootstrap/#/buttons

The right button in the right group is never rendered uncheckable.

Examining/tracing through the code, I think I can explain why it is not working and suggest a solution.
Lines 45-49 of buttons.js are intended to remove the uncheckable attribute from the element if uib-uncheckable evaluates to false. However, removing an attribute using attrs.$set(uncheckable, null) does not seem to work. It looks like the angular function$set()leaves the attribute key/value ofuncheckable="uncheckable"on theattrsobject. In line 37, a check is made to see ifuncheckableis present usingangular.isDefined(attrs.uncheckable). This seems to always returns true becauseuncheckable="uncheckable"evaluates touncheckable=null`.

You might need to remove the attribute from the element directly using removeAttribute() instead of using the angular function $set().

Let me know how I can help.

This does look like a bug - if you want to file a PR fixing this, it'd be welcome. Just let me know if you want to work on a fix - if not, I can take a deeper dive into it.
