Title: fixed indentation to write thumbnail preference

The pref_thumbnail_preview setting is not written to the config file if the exiftooloption is unchanged. Therefore, the config is always incomplete and the program asks on every startup to write a new one.
I think the options are unrelated and fixed the indentation.
