ipatests: ipa-acme-manage status returns 3 on a CA-less server
test_acme.py::TestACMECALess::test_enable_caless_to_cafull_replica is
running ipa-acme-manage status on a CA-less server and wrongly
expects retcode =1. According to the man page, the command returns 3
when executed on a server where the CA is not installed.
