test: remove third argument from assert.strictEqual()

In file test/parallel/test-stream-transform-final.js the ten calls to
assert.strictEqual() use a string literal as third argument. When
a AssertionError occurs, it reports the string literal and not the
first two arguments, so the third agrument is removed and made a
comment just above the call to assert.strictEqual().
