Some repo records is lost while saving

[macik]

[Thanks a lot for great plugin. And take my sadness that it's seems abandoned for some time.]

As I discovered, plugin can not support user defined repositories record for type artifact and path. So when I opened my composer.json with such a repos in list it's just skipped in result view of Plugin. And in this case if I save it, this user defined repo would be lost.
