Cannot call currentURL middleware reporter error

[drewlee]

Running ember-a11y-testing using the middleware reporter results in a precedent of tests failing with the Cannot call 'currentURL' error.

Cannot call `currentURL` without having first called `setupApplicationContext`."Source:
Error: Cannot call `currentURL` without having first called `setupApplicationContext`.
    at currentURL (https://localhost:4444/assets/test-support.js:21927:13)
    at middlewareReporter (https://localhost:4444/assets/test-support.js:31356:49)
    at async https://localhost:4444/assets/test-support.js:31289:11...

The exact reason is uncertain, as audits are invoked after setupApplicationTests is called. However, we should probably have better insulation where currentURL is called so that the entire test doesn't fall over when this error is encountered.
