Issue when patching connection with addition streams.

[SmitTailor27]

• I have created a connection with 1 stream for salesforce. (i have chosen all fields by specifying None as selected fields)
• Now i have to add more streams, so i am fetching the same connection and taking its response by GetConnection Method.
• In Response of connection i have got my previously selected stream. But in selected fields i got empty list instead of None, which is now creating issue when i am using PatchConnectionRequest where i am specifying addition streams.
• issue is due to that empty list is previously selected stream. if that selected fields value would be None that my PatchConnectionRequest would work.
