clean up PHP warnings

[dshanske]

I've been looking at this one. These lines relate to Quill doing a GET request for ?q=config

The plugin tries to authenticate for a config query. The specification is unclear as to whether that is required. But the issue comes

$auth = static::get_header( 'authorization' );
$token = $_POST['access_token'];

If there is not an access_token in the post, this generates an error.

yup, common pattern in this plugin, and PHP in general. i've cleaned up many similar issues in the micropub plugin, but not these in particular. low priority.

I will likely try after the other PR is done.

Resolved.
