mdPreventMenuClose: doesn't work with radio or checkbox type mdMenuItem

[diminutivesloop]

Setting the md-prevent-menu-close attribute on a md-button element fails to prevent the enclosing menu from closing when the button is clicked if the enclosing md-menu-item element has its type attribute set to either "radio" or "checkbox".

This issue is reproducible for Angular Material 1.0.7 across all major browsers.

Please verify this issue still exists in HEAD.

@topherfangio - it seems like this API is becoming complicated?

@ThomasBurleson Perhaps, but I think this is more of an issue with attempting to reuse the menu code within the menu-bar. The API should never have been available in the plain menu IMO.
