Bug 1276468 - Fix sheetToUrl function for inline style. r=jwalker

Browse Source 
The function was trying to access `stylesheet` parameter's ownerNode property,
which is undefined when the parameter is a StyleSheetActor. In the latter case,
we use nodeHref and styleSheetIndex properties to match what is done when the
parameter is a StyleSheet.
