Fix state restoration.

Fixes [this issue](https://github.com/wordpress-mobile/WordPress-iOS-Editor/issues/417).

I've noticed what seems to be a rendering issue while testing this PR.  Since it feels minor I've created a ticket for that problem [here](https://github.com/wordpress-mobile/WordPress-iOS-Editor/issues/424).

Things to test:
- Test Eric's recent private blog image upload fix.
- Test restoring never saved posts.
- Test restoring previously saved posts in view mode.
- Test restoring previously saved posts in edit mode.

Notes:
- The podfile.lock was updated for several files even though I only updated the editor pod.
