Null propagation operator was released in C# 6.0. Older versions of Unity use C# 4.0 which doesn't have null propagation operator. This leads to errors like this: `Assets/PocoSDK/PocoManager.cs(155,16): error CS1525: Unexpected symbol `.', expecting `[', or `identifier'`; `<Assembly-CSharp>\Assets\PocoSDK\PocoManager.cs:5345 Feature 'null propagating operator' is not available. Please use language version 6.0 or greater.` Documentation in README says that Poco-SDK supports Unity3D version 4 & 5 and above. To do this we should replace null propagation operator with the equivalent C# 4.0 code. This commit does it.
