Bug 27330: Return 403 if club has no enrollments

This patch makes the controller script return a 403 as it should [1]
instead of a plain 500.

To test:
1. Apply the regressions tests patch
2. Run:
   $ kshell
  k$ prove t/db_dependent/api/v1/clubs_holds.t
=> FAIL: Tests fail!
3. Apply this patch
4. Repeat 2
=> SUCCESS: Tests pass!
5. Sign off :-D
