Issue details

I successfully deployed a Release resource introduced in #1677. I then modified values in such a way that I expected it to remove 2 DaemonSet definitions. However when previewing it with those new values, it consistently fails with this panic:

$ pulumi preview
...
   panic: fatal: An assertion has failed
