fix(builtin.pickers): fix wrong picker resuming when using filtering (#2682)

When filtering is applied, `picker:get_index(picker:get_selection_row())` returns index relative to the filtered entry list rather than the original full results. This causes inaccurate indexing into the `cache_pickers` table.

(cherry picked from commit 74be3c3bba)
