Issue with assertQueryStringHas()

[iadambrown]

Just a heads up for anyone going through the last module, it seems there's an issue with the assertQueryStringHas assertion, due to a change to the assertHasQueryStringParameter method that it calls. Basically, assertHasQueryStringParameter now returns $this (i.e. the Laravel\Dusk\Browser object) instead of the $output array which contains the query string key/value pairs.

So having something like $browser->assertQueryStringHas('response_type', 'code') will cause a "Error: Cannot use object of type Laravel\Dusk\Browser as array" error when it gets to this part of the assertQueryStringHas method:

PHPUnit::assertEquals(
    $value, $output[$name],
    "Query string parameter [{$name}] had value [{$output[$name]}], but expected [{$value}]."
);

I've opened an issue here: laravel/dusk#455.

Here's the commit that causes the issue: laravel/dusk@fb67e61

Cheers!
