Add a test case to cover #3679 where a user migrates from a KSK/ZSK split using auto-dnssec maintain, to the default dnssec-policy (CSK). The test actually does not use the default dnssec-policy, but it does use one that has the same keys clause. For testing convenience, we use the same propagation time values as other test cases that migrate to dnssec-policy with mismatching existing key set.
