fix echo test handshake and reduce uart load 

1) if we receive more than one __sync, previous handshake would consider
it as echo_count and try to decode the value. Now we skip superfluous __sync.

2) reduce the uart load produced by the test, as we are heavily running tests in
parallel and not one-to-one this update was required.
