this change was made for sake of sorting, when the backend is not
responsible for that. in particular datetime values must be
"rendered" somehow when passing to frontend, but depending on various
factors the rendering may not preserve the "sensible" sort order
behavior, e.g. if "weekday name" begins the rendered string.
so in all cases now, rendered values will be given a distinct key in
the record dict, while the original value stays in its original
place. this should let grid sorting work off the original value, and
hopefully all is well..fingers crossed
