https://ci.concourse-ci.org/teams/main/pipelines/concourse/jobs/bosh-topgun/builds/469 is failing because of the fix in #3301.

The topgun test runs two identical get steps in quick succession, which causes two creating containers to be formed, but one of them is not required because that second get will end up finding the resource cache from the first one.

In addition, the second creating container is never removed from the db, which is also problematic.
