Preserve pathname when linking to individual tests in HTML reporter

[backspace]

When I use Mocha in the browser in an Ember CLI application via ember-cli-mocha, the links to run individual tests are broken. The tests run from here: http://localhost:4200/tests

The test links look like this:

<a href="?grep=Edit%20an%20issue">Edit an issue</a>

Sadly, an href beginning with ? doesn’t link to a query on the current path, but instead to a query on the root. In the above example, it links to http://localhost:4200/?grep=Edit%20an%20issue.

I can click the link and put /tests back at the beginning of the path, but this patch would fix the links for me and anyone using Mocha with Ember CLI. The tests all still pass, I can’t imagine it having a negative impact anywhere.

@backspace You wouldn't happen to be using firefox, would you?

I'm using Chrome. I failed to check it in other browsers, but my research indicates that linking to query parameters without a pathname links to the root instead of the current page.

OK, well I don't see an issue with this.
