Add log to understand flakiness of commands_test (#11720)

The flakiness of commands_test is generally visible via:

```
drive:stdout:   Expected: 'log: paint'
drive:stdout:     Actual: ''
drive:stdout:      Which: is different. Both strings start the same, but the actual value is missing the following trailing characters: log: paint ...
```

By returning the name of the test we will be able to understand if
another test is running by reading the `Actual` value
