Editing a queued post with quick edit switches the post to a scheduled post

[justinshreve]

Editing a queued post with quick edit switches the post to a scheduled post:

Steps to reproduce:

1. Create a new post and set it to queued.
2. Save the post.
3. From the posts list (queued page), edit the post with quick edit.
4. Save the post.

Expected behavior:

The post should remain queued.

Actual behavior:

The post is switched to scheduled.

In addition, the UI becomes screwed up, perhaps thanks to the addition of our extra column.
