Bug with AcmeDns plugin adding names to existing certificate in 3.3.0

[rmbolger]

The revamped plugin argument handling in Posh-ACME 3.3.0 partially broke the AcmeDns plugin when running New-PACertificate with additional names when there's an existing order with the same primary name. The previously saved AcmeDns registrations are wiped and replaced by the new ones rather than being merged with them. This results in the new request requiring new CNAMES for all names in the order that don't have a cached validation. If there are any names that do have cached validations, they will subsequently break renewals when those validations expire.

The plugin is now fixed in the dev branch. But unfortunately, users affected by the bug will still need to manually re-submit a new cert request in order to fix the underlying config. This will also mean updating the targets for CNAMES that currently exist because new registrations for each name will be needed.

The fix will go live in the next release.
