Tests: Allow statusText to be "success" in AJAX tests

mgol · web-flow · commit 19ced963c633 · 2021-12-01T12:46:17.000+01:00
In HTTP/2, status message is not supported and whatever is reported as statusText differs between browsers. In Chrome & Safari it's "success", in Firefox & IE it's "OK". So far "success" wasn't allowed. This made the tests pass locally if you're running an HTTP/1.1 server but on TestSwarm which is now proxied via an HTTP/2-equipped Cloudflare, the relevant test started failing in Chrome & Safari. Allow "success" to resolve the issue. Closes gh-4973
