-u flag causes chrome driver error

**Bug**

When running a test, the `-u` command causes a chrome driver error. Running the same command without the `-u` flag succeeds.

- `dojo test -u -c local` / `dojo test -u -c headless` - Fails
- `dojo test -c local` / `dojo test -c headless` - Passes

Platform: Window 10
Package Version: 7.0.0-alpha.6

**Code**

https://github.com/dojo/examples/tree/master/dgrid-wrapper

**Expected behavior:**

Tests should run successfully.

**Actual behavior:**

```
