Bug 29736: Restore searching

Without this patch, the list will always display all clubs.

To test:
1. Have two clubs, with enrollemnts:
   - Cthulhu fans
   - The Shadow Out of Time fans
2. Search for the letter c
=> FAIL: You get both results
3. Apply this patch
4. Repeat 2
=> SUCCESS: Only Cthulhu is returned
5. Sign off :-D
