Description of problem:
When setting up a KubeVirt Compute Resource and clicking "Test Connection" without providing a name for the CR, a green "Success: Test connection was successful" pops up in the right hand corner, even if the connection is not valid (e.g. bad credentials)
 

How reproducible:
100%
 

Is this issue a regression from an earlier version:
No
 

Steps to Reproduce:

1. go to /compute_resources/new
2. select kubevirt/openshift virt as the provider
3. enter something for hostname, api port, namespace, token
4. leave name blank
5. click "Test Connection"

Actual behavior:

• "Test connection was successful" in the right upper corner
• The button does not turn green (as the test actually fails)

Expected behavior:

• No "Test connection was successful" popup
