…(#3012)

Current changes to the ``framework.js`` led to a breaking change due to the fact, that ``options.data`` was no longer populated with the request data. The ``options`` object is part of the ``context`` object, which is later beeing passed to ``ajaxBeforeSend``
The two relevant versions of the file show the change of behavior:
https://github.com/octobercms/october/blob/b6fedfb688e2d99461fd62b99bc8412f38502180/modules/system/assets/js/framework.js#L56 => https://github.com/octobercms/october/blob/develop/modules/system/assets/js/framework.js#L88
The change is required to remain consistent with the old behavior. This code is tested and appears to be working as it did formerly.
