AssertionError in flow/flow_lib/node.js is missing assert.fail([message])

[assert.fail([message])](https://nodejs.org/api/assert.html#assert_assert_fail_message) is missing, but the deprecated
[assert.fail(actual, expected[, message[, operator[, stackStartFn]]])](https://nodejs.org/api/assert.html#assert_assert_fail_actual_expected_message_operator_stackstartfn) syntax exists. So my correct use of the function is being flagged by the flow type checker.
