Nutrition stats missing

[muety]

Thankfully, nutrition stats were introduced in #124 to the app. However, I noticed that they're missing quite frequently, even though available on the official website. I can't provide a clear way to "reproduce" this, but here's an exemplary screenshot. I'd say this happens almost daily for a subset of meals. Perhaps something's wrong with the scraper?

Thanks for this report. This is also something I occasionally noticed. Investigating this, I discovered an issue when updating the nutritional and environmental data in the database: Existing meals without some of this nut/env data (from before this update) did not get an entry created in the new tables for nut/env data.
