Title: fix format guessing in Chooser::addFile()

The `guess()` method from the `FormatGuesserInterface` does not return a `FormatInterface`, but returns a `FormatChainInterface` instance instead.

@raulfraile I'm not sure if it's best to throw a `FileUnknownFormatException` here if no format could be guessed. What do you think?
