[posila][0.18.6] Rocket silo does not show items in output slot in tooltip

[wladekb]

All the assemblers list the stored products in the tooltip in the "Contents:" section as seen here:

Unfortunately resource silo (which is a kind of producer too) does not list it as seen here (no white science packs in the "Contents:" list):

It would be much more consistent if the products were listed in the resource silo "Contents" section as they are in assemblers.
