Clean up code in navbar (#2912)

* Cleaned up code in navbar

- Replaced many ifs with the 'in_array' native PHP function to set item in navbar active or not

* Fix Log item not being set as active in navbar

- Log item is never set as active in navbar. When using the `admin` account the `server` item is set as active (when accessing logs via Server -> Logs) because it uses a query string setting the user as `system`. Now it will keep this behavior but when no user is set via query string the Log item will be set as active.
