Feature/xx 4450/fix integration

Summary: This partially fixes integration, specifically two bugs.

2. Integration tests for channels were consistently failing, I determined there was a bug in the cmd/ path where the program could close before receiving all it's messages. I added some logic to wait for messages to be received or timeout and fail
