Bug 26994: List names in alphabetical order in Suggestion filter

Display list of names in alphabetical order when using the Suggestion information filter in Suggestions management

Test plan:
1. Add different purchase suggestions from various patron's names
2. Go to Acquisition > Suggestions
3. Click on the Suggestion information filters on the left-hand side
4. Use one of these drop-down menus: "Suggested by" or, "Managed by" or "Accepted by"
--> notice the list of names in menus, names aren't displayed from A to Z
5. Apply patch and refresh page
6. Redo step 4
--> notice now it's sorted alphabetically
