Navigation scrollbar not present if in production mode

[Robert Lyon]

If we are in production mode and there are no site messages at top of screen then the navigation menu doesn't have the scrollbar option when long menu list

This was an oversight in bug https://bugs.launchpad.net/mahara/+bug/1765276

To test - have a site in production mode then look at the admin -> Institution navigation menu when browser port is smallish in height
