fix(json-loader): pass decoded config to loader instead of empty map

The Phase B stub discarded the decoded PhpMixed and handed an empty
IndexMap to LoaderInterface::load, so nothing was actually loaded.
Unbox PhpMixed::Array into the map; mirror PHP's array $config type
juggling by raising a TypeError for non-array decode results.
