Store and update post status in dt object.

Description of the Change

Fixes a bug introduced during the 2.0.0 release cycle in which unchecking the send as draft checkbox would cause an error for posts that had changed status while the editor was open.

Fixes #141
Follow up to #1022

Note

The custom Cypress distributorPushPost command automatically reloads to page before attempting to distribute (this allows us to distribute a post ID from anywhere). I tried to use cy.url() to only refresh pages when needed but without success.

Any assistance here would be most helpful.

How to test the Change

1. Create and publish a new post
2. The Distributor menu will appear
3. Hover over the menu, select a destination to push to
4. Uncheck the "Send as draft" checkbox
5. Click "Distribute"

On this branch the post should successfully distribute. On develop the post will:

• show an error for external connections
• apparently succeed for network connections but if you visit the site's admin the post will not appear.

Changelog Entry

Just add this PR to the existing entry Toggles the Distributor admin bar element in Gutenberg based on the post status
