Do not show deleted papers on admin dashboard

The Problem
The main list of (unapproved) papers on the admin dashboard is only loaded once on page load. Once papers are approved, the local state is updated and on the UI they are highlighted green. However, no indicator is there for papers which had been loaded earlier and have been deleted since (by use of the replace feature).

Possible solutions
Either highlight these differently and also show an indicator on the edit modal, or better would be to remove these papers from the local state. However this might have complications as it messes up indices of papers in the array, which is also used in local state.

I suppose normal removal from the array should be fine, as that's how the normal delete button works.
