test(e2e): assert the duplicate-name refusal directly

oxlint's playwright/no-conditional-in-test was right to object: branching on whether
Save happened to be enabled meant the test asserted one of two things and reported
neither. It is disabled — the form refuses the duplicate outright — so assert that,
and keep the check that no second variable of that name exists.
