PVF: Remove artifact persistence across restarts (#2895)

Considering the complexity of #2871 and the discussion therein, as well as the further complexity introduced by the hardening in #2742, as well as the eventual replacement of wasmtime by PolkaVM, it seems best to remove this persistence as it is creating more problems than it solves. ## Related Closes #2863
