Author filter missing from post/page list the first time the screen is shown

[guarani]

Expected behavior

On a multi-author site, the Post List and Page List screens should always show an author filter with the options "Me" and "Everyone".

Actual behavior

On opening the Post List screen, I don't see an author filter at all. When I close the screen and reopen it, I now see the author filter.

Steps to reproduce the behavior

1. Log in to a WP.com account that has access to a multi-author site (logging into a multi-author self-hosted site could work as well)
2. Open the Post List and notice the missing author filter
3. Tap the back button and re-enter the Post List
4. Notice the author filter is now shown
