renaming a DNS record to a previous name fails with error: list.remove(x): x not in list

[Alberto Donato]

The following fails with the "list.remove(x): x not in list" error:

- create an A record in a domain with name "test"
- edit the entry and rename to "test-new"
- edit the entry and rename to "test" again -> fails

This is somewhat similar to https://bugs.launchpad.net/maas/+bug/1894894

[Alberto Donato (ack)]

I think this is another incarnation of LP:1894894, (see https://bugs.launchpad.net/maas/+bug/1894894/comments/3) specifically for the cause

[Alberto Donato (ack)]

On a related notice, the UI callse "domain.delete_address_record" to remove the entry, but this only deletes the address, not the dnsresource, so the original one ("test" in the example above) is still there, without any address.

When attempting to revert to the old name, the entry is found, so the logic tries to remove the old address (which hasn't really changed), triggering the error.

This landed in maas-ui via https://github.com/canonical/maas-ui/pull/4571 and got pulled into MAAS itself in https://git.launchpad.net/maas/commit/?id=3991bca8971dea46dca3d0786557458644a79317

This is fix released on the maas-ui side.

As we cannot change the status for the maas-ui project for imported items, I'll remove the dependency to maas-ui.
