etcdutl: add cases to hashkv_command_test

[silentred]

Please read https://github.com/etcd-io/etcd/blob/main/CONTRIBUTING.md#contribution-flow.

The root cause in #21106 is that when there are keys with leases in db, the recovering process of store panics at https://github.com/etcd-io/etcd/blob/main/server/storage/mvcc/kvstore.go#L395 , before attaching keys to leases.
Therefore, I added a case to hashkv_command_test for the scenario described above.

Hi @silentred. Thanks for your PR.

I'm waiting for a etcd-io member to verify that this patch is reasonable to test. If it is, they should reply with /ok-to-test on its own line. Until that is done, I will not automatically test new commits in this PR, but the usual testing commands by org members will still work. Regular contributors should join the org to skip this step.

Once the patch is verified, the new status will be reflected by the ok-to-test label.

I understand the commands that are listed here.
