Prevent IE9 and lower displaying the download file dialogue when attempting to upload using the html4 Plupload handler.

Browse Source 
The HTML4 Plupload handler uses a hidden iframe to POST the upload form,
Unfortunately Internet Explorer 9 doesn't support the `application/json` 
content-type which `wp_send_json_success()` and requires `text/html` instead.

This partially reverts [30354], keeping the better error messages.

Fixes #31037 for trunk.
