We run interop test for Openshift and Ansible Tower projects. We are able to install Openshift cluster with the installer into the GCP environment, but after completing the test we cannot destroy the cluster in most cases.  

The destroy command failed with the 
Runtime error: slice bounds out of range [:22] with length 21. 

(see destroy.log attached)


What did you expect to happen?

Installer should be able to destroy the cluster.

How to reproduce it (as minimally and precisely as possible)?

# Create install-config.yaml file

```

# Configure GCP authentication so the installer can communicate to the google cloud.

# Run installer to install cluster into the GCP 
$ openshift-install create cluster --dir=.

# After deployment is completer try to destroy the cluster
$ openshift-install destroy cluster --dir=.
