User job title sort will not order correctly when there contains empty values. This is a problem with bobo-browse (third party app) with how they handle sorting on null fields.

To reproduce:
1) Add 10 users
2) Every other user should contain a job title. (5 users contains job titles, 5 users contain empty job titles)
3) View the users either through Directory portlet or User view screen (Control panel)
4) Sort by job title
Issue: You'll notice that job title sorting is off. Blank job titles are not sorting correctly.

What should happen: The job title should sort correctly.
