Creating a post does not create a revision #564

When testing #563 I realized there's a difference in behavior for revisions between wp-admin vs WP-CLI.

In the block editor, when I publish a new post, there are 2 new entries in wp_posts: one for the post (ID 1), and one for an identical revision (ID 2). When I then update the post with ID 1, a new revision (ID 3) is added. This way, I can easily restore the original content by restoring post with ID 2.

With WP-CLI, when I run wp post create, only one entry is added (ID 1). No revision. When I then make an edit, a revision is created for the edit, but the original content is lost.
