Group label does not pick up MIP classes on initialisation

> We've hit a snag with the recent changes to the handling of group labels.
>  
> As things currently stand, the group label is always rendered with a
> class of "xforms-label" regardless of any MIPs that the group might have.
>  
> An effect of this is that, if the group is non-relevant initially, its
> label still shows even though the contents of the group do not.
>  
> Subsequent changes to the relevance of the group correctly show and hide
> the label along with the group.  See the attached file for a sandbox
> example.
>  
> The cause is the line
>  
>              reusableAttributes.addAttribute("", "class", "class",
> ContentHandlerHelper.CDATA, "xforms-label"));
> in XFormsGroupHandler.java, which doesn't incorporate either MIPs or
> existing classes on the label element.
