This patch changes Page.navigate API:
- Page.navigate now resolves to the main page response
- Page.navigate throws errors if there's no main page response,
e.g. in case of SSL errors, max navigation timeout,
or invalid url.
This patch also adds httpsServer with a self-signed certificates
for the testing purposes.
Fixes#10.
This patch:
- Changes network idle promise to wait for 2 or fewer network requests for at least idleTime (defaults to 5s) before resolving.
- Adds timer cleanup to failure navigation case.
- Adds handling of webSocketClosed.
- Ignores unrecognized requestIds to avoid negative inflight requests.
