Three uses of `hasOwnProperty.call` have been replaced with simpler alternatives. I did this because I found this convention confusing. The `ComposableObservableStore` changes required adding a check for whether the `config` is defined, because the old syntax would allow iterating over `undefined` as if it was an empty object. Functionally it should be identical. A new test was added to highlight this functionality.
