Anonymous users cannot add status to a page

Issue Summary

Currently, anonymous users are unable to set a status do page.

Steps to Reproduce

1. As an anonymous user, create a page in a Confluence Cloud space that's being shared with Anonymous Access
2. Select "Set page status"
3. There's only the option to create a custom status - try to add it 

Expected Results

Anonymous users should be able to select a status for the page.

Actual Results

Anonymous users cannot select a status for the page. Even though there's only the option to add a custom status, not even this is working and an error message gets displayed: 

 java.lang.NullPointerException: Cannot invoke \"com.atlassian.confluence.user.ConfluenceUser.getAccountIdAsString()\" because \"user\" is null",
                "path": [
                    "availableContentStates"

Workaround

Currently, the workaround would be to ask for a logged-in user to add the status to the page. But, at this moment, only custom status can be used on pages created by anonymous users (CONFCLOUD-78384).
