Issue: Native part of WebView throws a DOMException and then, continues executing the rest of the function assuming that value is present. This causes the JVM to crash when retrieving the value.

Fix: Return from the function if exception was raised (code is similar to exception handling in [WebKitLegacy/java/DOM/JavaTreeWalker.cpp](https://github.com/openjdk/jfx/blob/master/modules/javafx.web/src/main/native/Source/WebKitLegacy/java/DOM/JavaTreeWalker.cpp))

This fix also needs to be applied to all function calls in [WebKitLegacy/java/DOM](https://github.com/openjdk/jfx/tree/master/modules/javafx.web/src/main/native/Source/WebKitLegacy/java/DOM) functions which raises DOMError similar to createAttributeImpl().
