MetadataBindingUtils does not respect ODataUriResolver.EnableCaseInsensitive

[wertzui]

When checking if a provided string is a valid enum member, the method SingleValue always uses StringComparison.Ordinal in Line 67 instead of looking at ODataUriResolver.EnableCaseInsensitive and using a case insensitive comparison if it is true.
