More resilience with "Failed host lookup: 'static.openfoodfacts.org'" (svg icons)

[sentry-io]

Sentry Issue: SMOOTHIE-46M

Sometimes, for some reason we don't manage to retrieve svg icons from the server.
Not a big deal for Smoothie, as we have a local fallback icon.
The problem is that we get flooded by related sentry errors (all icons failing in the same session), that are relatively harmless but may hide more important but less common issues - just by being the top sentry errors.
A solution would be to sent only one "Failed host lookup: static..." by session. We'll still get the annoying message that the server wasn't reachable, but with more parcimony.

OSError: OS Error: No address associated with hostname, errno = 7
ClientException: ClientException with SocketException: Failed host lookup: 'static.openfoodfacts.org' (OS Error: No address associated with hostname, errno = 7), uri=https://static.openfoodfacts.org/images/icons/dist/car.svg

Supposed to be closed since... March 4th.
Too bad we only released it 9 months later in 4.17.0.
