Removed auto_incrementing id and set a primary key of the [role_id,
entity_type, entity_id, action] instead since this table could recieve a
lot of activity, especially when permission regeneration was automated,
leading to very high auto_increment counts which could max out the
integer limit.
Also updated some RolesTest comment endpoints to align with
recent route changes.

Fixes permissions with test to cover in the event a page is created,
with permission, in a chapter but the user does not have permission to
see the parent book.
Fixes#912
Updated elements of a page display and sidebar render to allow
child permissions to work even when parent entitites have permission
set. This allows a page with a 'view' permission to be viewable even
when the parent book or chapter is not viewable.
Fixes#366
