    Revert "Detach volume after deleting instance with no host"

    This reverts commit 5ce74fa06c0e7a70fdc927b2c1f364af83f7de1d.

    We think this is causing a race and the postgres job to fail
    since it's erroneously doing local deletes and not cleaning
    up from the computes. We're not totally sure why it would
    only impact the postgres job though, but the original change
    failed the job and was rechecked, and the time it was merged
    coincides with when the postgres job started spiking with
    failures.
