Jenkinsfile: destroy the VM last in the build
Jenkinsfile: destroy the VM last in the build

We are only destroying the VM when we start a build, which means
that for pull requests, when the request is merged, a build is
not built more times, which leaves the VM hanging. If we destroy
it in the end of the run as well, we should not get this problem.
