Rather than having store implementations return a free-form URI string, have them return a `StoreReference`. This reflects that fact that this method is supposed to invert `resolveStoreConfig`, which goes from a `StoreReference` to some `StoreConfig` concrete derived class (based on the registry). `StoreConfig::getUri` is kept only as a convenience for the common case that we want to immediately render the `StoreReference`. A few tests were changed to use `local://` not `local`, since `StoreReference` does not encode the `local` and `daemon` shorthands (and instead desugars them to `local://` and `unix://` right away). I think that is fine. `local` and `daemon` still work as input.
