AES-GCM integration with webcrypto brakes when optional param not sent

[antonioconselheiro]

When a cipher is generated with AES-GCM using integration with webcrypto, the third parameter of the gcm function, ADD, is optional, however undefined is not accepted by the webcrypto API and error is launched. It didn't happen in nodejs, only in a browser environment.

See the reproduction of the bug:
