The class reads existing config, but in the upgrade path from Open
Social 10 to 11 the config schema is changed, so the array element we're
trying to read might not exist. This causes warnings in the upgrade
path.
We ignore the setting if it doesn't exist because it means we're working with the old config. The config override will be reloaded after the post-update cache-clear which ensures the proper override is applied.
