Fix the config get request

[valpackett]

The spec says it's GET /micropub?q=config, but Quill is STILL doing GET /micropub!

Quill/controllers/auth.php

Line 217 in dbb17a5

get_micropub_config($user);

get_micropub_config called without any query

Quill/lib/helpers.php

Line 210 in dbb17a5

function get_micropub_config(&$user, $query=[]) {

default query is blank!
