Fix: CI Droplet cleanup failed when same name was used

[hoh]

When there were multiple Droplets with the same name, cleanup using doctl compute droplet delete -f $NAME would not work.

Error: There are 3 Droplets with the name "aleph-vm-ci-XXX"; please provide a specific Droplet ID. [425559566, 425702949, 425703724]
