…ormat but PFDecoder.m checks for __type key which is missing as shown in below example so this fix will add "__type ":"Object" key-value if dictionary has className and objectId representing PFObject.

Issue Description
Response from websocket server does not include "__type":"Object" but PFDecoder expects this otherwise events failed to be caught.
Closes: Issue #1832
Approach
LiveryQuery server response sends data or events in "object":jsonf= format but PFDecoder.m checks for __type key which is missing as shown in below example so this fix will add "__type ":"Object" key-value if dictionary has className and objectId representing PFObject.
Requesting review.
