416706 Krita last-used filter is loaded even using the Menu Filter

• Update LastUsedFilter when filter is applied

  Before, the value was only updated when selecting a filter from the list.

• Don't load LastUsedFilter using Menu Filter

  When the filter was called from the Menu, we dont load the LastUsedFilter as we change the filter later and some filters may take a long time to process.

  BUG:416706
