Fix sdlcli get -command result stdout write
Sdlcli get -command writes wrongly results to stderr stream. Fix sdlcli
get -command to write results to stdout stream when command execution
has succeeded. In addition add similar stdout redirect also to sdlcli
statistics -command just to keep the code look the same, even thought
there wasn't any real issue with sdlcli statistics -command's results
visibility.
