Flow errors in middleware.js

[femiveys]

Commit 4731556 has introduced flow errors in middleware.js.

On line 9 we have:
Cannot import getNavigationActionCreators because there is no getNavigationActionCreators export in react-navigation.

Online 99 we have:
Cannot assign object literal to navigation because property state is not writable in property state.

Can this be fixed?

This is blocked on this PR, which should hopefully get merged early next week. For now, either use the libdef from that PR, or downgrade to an earlier version of react-navigation-redux-helpers.
