Filter json-only KFileItemAction plugins by mimetype

Commit d48b733 introduced support for kfileitemaction plugins with json
metadata, but forgot to filter them by the commonMimeType (like
KMimeTypeTrader::query() does with old-style plugins).

So we need to load a plugin only when commonMimeType is equal to (or child of) one
of the mimetypes supported by the plugin.
