 There are a number of times that $_GET is required to retrieve parameters.
 Within `WP_REST_Server::serve_request()` the following code sets up a
 request object:

 {{{#!php
 $request = new WP_REST_Request( $_SERVER['REQUEST_METHOD'], $path );

 $request->set_query_params( wp_unslash( $_GET ) );
 $request->set_body_params( wp_unslash( $_POST ) );
 }}}

 If this request could be added to a `last_request` property then
 parameters can be retrieved by code like
 `$this->last_request->get_query_params()`.  This eliminates the need to
 retrieve values using $_GET and also makes Unit Tests a lot nicer.
