fix(uninstall): supersede deployed releases

This ensures that when `helm uninstall` is run with `--keep-history`
any release in a `deployed` state other than the last release (e.g.
due to a failed upgrade) is being marked as `superseded`.

As a by-effect, running `helm upgrade` on a release which has been
uninstalled after an upgrade failure now no longer works. But instead
fails with a `"<name>" has no deployed releases` error. Which is the
(likely) intended behavior, and prevents other side-effects like
rolling back to a release version which happened before the uninstall
if `--atomic` (or `--rollback-on-failure`) was provided.
