0.4.0 silences errors

[koo5]

when a query ends up with a graphql error, nothing shows up in the console. And there isnt {:catch error} anymore.

ah:

// Match Apollo's hook approach, by returning a result with three states:
// loading, error, or data (where data could be null / undefined)

export interface Loading {
    loading: true;
    data?: undefined;
    error?: undefined;
}
