problem:  XMLHTTPRequest POSTs blob data to a custom WKURLSchemeHandler protocol will make wkwebview UIProcess crash，The cause of the crash is that the blobRegistry was not initialized


Steps:

1、 Setup custom Scheme
    TestWKURLSchemeHandler *handler = [[TestWKURLSchemeHandler alloc] init];   
    [configuration setURLSchemeHandler:handler forURLScheme:@"test"];


2、launch the  iOS Simultaor 

3、load with url: test://aaa/blobdemo.html 
```
<!DOCTYPE html>
<html>
<head>
<title>blob demo</title>
</head>
<body>
   <script type="text/javascript">
     var blob = new Blob(['blob ', 'foo ', 'bar '], { type: 'plain/text2', endings: 'native' });
     var request = new XMLHttpRequest();
     request.open("POST", "/testblob");
     request.send(blob);
   </script>    
</body>
</html>
```

4、Send a  *blob* XMLHttpRequest with the custom scheme

Result：

UIProcess crash
