[Plugin: Organize Series] PHP warning on foreach() invalid argument

You don’t need to fix this urgently because nothing is broken, there is just some code there where the foreach is expecting a value that isn’t present.

With that said, thanks for pointing this out because I do aim to not have ANY PHP warnings/errors and I’ve added a fix that will remove this warning in future released versions of Organize Series. Hopefully by this weekend I’ll release the next version.

Thanks!
