Ahmet Alp Balkan 70407ce40c Better test cleanup with defer
This fixes a few misuses of `deleteAllContainers()` cleanup
method in integration-cli suite by moving call to the
beginning of the method and guaranteeing their execution
(including panics) with `defer`s.

Also added some forgotten cleanup calls while I'm at it.
