ipa cert-find command does not find arbitrary certificates which were added using {user|host|service|iduseroverride}-cert-add command.

Steps to reproduce:
1) Add certificate using user-add-cert command
2) Try to show certificates for user using $ ipa cert-find --users username
3) No certificates match
4) Try to show certificates for user using $ ipa cert-find --users username --sizelimit=0
5) 1 certificate matches

The same issue (no arbitrary certificates) is also for cert-find without specifying user or any other entity.

Expected result:
Certificates are found even without --sizelimit=0
