Running unit browser tests on windows starts IE instead of Chrome

[liza-mae]

Currently the browser unit tests are trying to run IE, but our tests use Chrome right now. Should it be using Chrome? If so, need to fix it to point to Chrome. Also when IE is supported, we need to fix this.

Part of issue: #21315

In theory these should work in IE on Windows platforms since they aren't using the functional test runner? But I never had them work for me on Windows/IE.
