Fix Watch follow parameter detection

The generated client now emits parameter names and types on separate
lines. Watch still searches for the old combined line, so it sends
watch=True to pod log methods and the generated client rejects the
unexpected keyword.

Match the current generated format and update the fixture that covers
log streaming.
