Update deps to new hapi scope

[zemccartney]

Addresses #13

@devinivy I added the odd new lines in the testing file to deal with that test failing on node 10 (v.10.15.3) and 12 (v.12.2.0).

The test would complete, all assertions would pass, but would then error out in the onCleanup callback with an ECONNRESET error. As far as I can tell, this happens because the http2 client's response stream hasn't closed, so calling client.destroy() force-ends that stream, triggering an ECONNRESET. Note that calling client.close(), the "graceful/clean" version of that call, closes the stream without error (though takes some extra time to complete).

The current approach ensures the response closes by consuming it via the data handler, which seems to enable the stream to end (without the data handler, the Toys.event(request, 'end') never fulfills, causing the test to timeout. I think? God, I dunno, very quickly got out of my depth.

My bad if I just made a mess of things here

Sounds reasonable to me! Thanks.
