[log] Remove the obsolete NoGraphTableModel & simplify the code which used to use it
[log] IDEA-121817 Fix keeping selection

* Collect selected commit indices before updating the facade (applying
  filters) or the DataPack (refreshing).
* Apply them, as previously, after installing the new model.
* Since we don't have NoGraphTableModel anymore, use commit indices
  instead of Hashes to avoid extra conversions.
