@dannywillems Moved + modified test_lookup_with_a_table_with_id_zero_but_no_zero_entry so that it catches the has_zero_entry bug that this PR fixes.

Here's a run with the new test but old has_zero_entry showing that the bug is caught successfully:

test tests::lookup::test_lookup_with_a_table_with_id_zero_but_no_zero_entry - should panic ... FAILED

failures:

Do you want me to create corresponding mina/o1js PRs for this one?
