Using SC.get('/resolve') returns an error on Firefox #90
Description
(Javascript SDK)
When using SC.get('/resolve', {url: foo}) on FIrefox, a first OPTIONS request is sent which causes the initial call to '/resolve' to return an error in the promise.
A workaround I found was to use SC.resolve(URL) directly, which sets _status_code_map: { 302: 200 } in the request's options.
Maybe this option should be there by default on the SC.get() method as well?
