Improve error handling for JToken property access

[lahma]

• we can always ignore Symbol properties for CLR objects, they don't exist
• InvalidOperationException is something like the ArgumentOutOfRangeException and IndexOutOfRangeException which we already ignore

fixes #795

I'm getting error Accessed JArray values with invalid key value: "0". Int32 array index expected when trying to access property of JObject.

Hope we can get it fixed soon.

After took deeper look at the source. I get some clue and made an ugly fix for my situation.
