Please include the exceptionTypeName in the JsonRPCError exception message

[thaen]

In most exceptions I've seen, the actual Java exception class name (like "com.android.uiautomator.core.UiObjectNotFoundException") is in the jsonresult that is received in JsonRPCMethod.call but it is thrown away when the wrapper exception JsonRPCError is created. It is trivial to include and greatly increases the readability of the exception. This has worked for me:

        if "error" in jsonresult and jsonresult["error"]:
            raise JsonRPCError(jsonresult["error"]["code"],
                   (jsonresult["error"]["data"]["exceptionTypeName"] +
                ": " +
                                jsonresult["error"]["message"]))
        return jsonresult["result"]

I'll eventually get around to submitting a patch but it might be easier for something else who is more familiar with all the exceptions that can be thrown to fix it.
