Redux-devtools: Bad error when you forget to pass empty config to __REDUX_DEVTOOLS_EXTENSION_COMPOSE__()

[RyanAtViceSoftware]

Hi,

I'd be happy to PR this if someone points me to the correct file but currently if you forget to pass an empty config object to __REDUX_DEVTOOLS_EXTENSION_COMPOSE__({}) you get a really vague error and this could make finding the problem really hard as the app never starts, you don't end up with a useful stacktrace and the error is below. I'd propose adding an error that explains the problem or even better might be to just default the first parameter to empty object.

Uncaught TypeError: a.subscribe is not a function

I think you're looking for redux-devtools-extension.
