This is quite a lot of boilerplate but we don't have that many tests so I'm not sure if this is the moment to generalize it... If there's a way to simplify, I'm all ears. :)

The special + handling is not documented at https://api.jquery.com/jQuery.ajaxPrefilter/, I found it by reading source. 🙈

Note to self - jQuery.when is unavailable in jQuery 4.x Slim. Perhaps it's better to use a Promise polyfill like native-promise-only that we already use in Core tests.
