Fix a crash with BlockingCollection in Connection

Browse Source 
The BlockingCollection would have `IsAddingCompleted` to true, but `IsComplete` to false, slipping through the cracks and causing an InvalidOperationException ("The collection has been marked as complete with regards to additions.") when trying to add to it.
We now add a check on `(Try)SendData` to only try to add if we can. The collection is still viable for reading until empty/`IsComplete`.
