When evaluating the potential "warning" key from the json output we were
not hiding stdout (1) from the output, so the key was leaked. Also the
warning check for the key was not perfect, it only checked for the
command to succeed, but we should introspect it since the "warning" key
is always present unlike the "error" one.
We now only print the warning or the error is present.
