Fix #627

Docker-py couldn't pull private images if the account have non ascii chars
in either user or password. It that case an exception ending with no auth
credentials.
Instead docker client (golang) don't suffer this issue.

Also add a test to check the login or password even with non ascii char have
a valid auth dictionary
