Search is not returning pages where only the edit permission is granted

Issue Summary

Search does not return pages with view and edit restrictions, where the view permission has been removed from the restricted permission page and only the edit permission remains for a user/group.

Steps to Reproduce

1. Setup a page with view and edit restrictions
2. Add a user/group with view permissions
3. Add a user/group with edit permissions 
4. View the restricted page permissions via: https://instance.atlassian.net/wiki/pages/listpermissionpages.action 
5. Remove (click the lock icon) beside the view permission for the user/group with edit permissions
6. The user/group can still view the page
7. If this user/group searches for the page it will not be returned in the search results (the search functionality explicitly requires the view permission to return the page)

Expected Results

The view and edit restricted page should still be returned in the search results for a user/group that has only edit permissions (since the view permission is included in the edit permission for viewing the page).

Actual Results

The view and edit restricted page is not returned in the search results for a user/group that has only edit permissions.

Workaround

Use the lock icon on the page to manage access and add the user/group to have view permission to the page.
