test(stock): use db-agnostic index introspection in Item index test

test_index_creation used `frappe.db.sql("show index from tabItem")` and the MySQL-only
result key "Column_name". "SHOW INDEX" errors on Postgres, so the test could not run
there. Use the db-agnostic frappe.db.get_column_index("tabItem", column) (checking both
unique and non-unique single-column indexes) instead.
