[Bug] No useful error message is presented when Docker registry doesn't exist #1

When running bob push and the image has an inexistent registry Docker retries it several times:

The push refers to repository [inexistent-repo/image:tag]

EOF
As you can see, at the end it just prints an EOF. Since our build considers only what's returned in the last line, we should improve the log when this happens.
Maybe something like
if lastLine == "EOF" {
log(better message)
}
