Ensured that store from props is initialized with initialize from props.

[thchia]

This addresses the 'provider initialization failure' in #135 .

Problem

When both store and initialize are passed to LocalizeProvider, the store is not initialized with the passed payload.

If initialize is omitted, this problem does not occur because the initialize() function is called from userland (from the withLocalize-wrapped component). This explicitly dispatches the initialize action.

If store is omitted, this problem does not occur because there is already code to initialize the passed payload into LocalizeProvider's state.

Changes

I have added a method that initializes the passed store with the passed initialize payload (if both are present), and call it in componentDidMount. Since there are more things happening in componentDidMount as a result of this, I extracted the existing code (subscribe to store) to a separate method. I have also added a test.

I think some parts of this diff are caused by prettier not being run somewhere in the past. The new test is at the end of the test file.
