An event was not called on uploading files in a media dialog.
This meant the parent of html field didn't know of the new attachments
which resulted in attachments being linked to no record at all
and not being garbage collected later.
This adds a reference inside the media dialog file input so that it can
trigger that event on behalf of the html field.
The attachments newly uploaded in media dialog are uneditable
to prevent users from unlinking attachments
that are still used in the body of the composer (causing the same issue)
