core.configmanager: Fix reporting delayed warnings from global section A Credential in the global section would be stored at delayed_warnings["*/secret"], but get("example.com","secret") would look for delayed_warnings["example.com/secret"] Storing the warnings in the config itself has the unfortunate side-effect that the config now contains util.error objects, which may be awkward if something bypasses get(). Should rawget() also do this filtering? getconfig() too? Currently this only affects prosodyctl, so maybe it won't be much of a problem.
