Fix Redux Store flow errors

[richardgirges]

The fix

This should fix the Redux-related flowtype errors that are popping up in react-apollo due to incorrect usage of the Redux Store type in index.js.flow.

The error currently appears as:

node_modules/react-apollo/index.js.flow:30
 30:     store: Store,
                ^^^^^ Store. Application of polymorphic type needs <list of 2 arguments>. (Can use `*` for inferrable ones)

This fix is basically adding inferred types (*) as arguments to all references to the Redux Store type inside of index.js.flow. This should fix #898.

Additional Details

Generally you want to pass in your State and Actions as arguments to Store. i.e.:

type State = {
  // ...
}

type Actions = {
  // ...
}

const foo: Store<State, Actions> = // ...

... but seeing as how the usage of Store was incorrect to begin with, and in one area, there was a Store<any>, I figured this is a decent step forward in correctly typing this aspect of react-apollo.

If perhaps this is not the right approach to fixing this flow error (i.e. maybe we want to somehow be more explicit about the Redux State and Action arguments, feel free to toss this PR out.

@richardgirges thank you for this! In an upcoming release react-apollo/apollo won't depend on redux anymore but I will cut a release with this for now! Thank you again!

Non-redux dependence FTW! Thanks for merging in the meantime @jbaxleyiii :D
