Title: Print explicit error when trying to config a phone or image already on B2G

Here is another issue I had. It wasn't really obvious why the config.sh script failed.
Me and David both tried to hack the extract_file.sh instead of realizing we were totally wrong!!

Even if it is explicitely mentioned in documentation it would be worth printing such explicit message.
