1311739 - Push H/2 test improvements

Status: RESOLVED FIXED

(Core :: DOM: Push Notifications, defect)

Description

[:Lina Cambridge]

:hurley has a Try run where several of the Push H/2 tests time out. A few things stand out from the log at https://archive.mozilla.org/pub/firefox/try-builds/[e-mail]-b66f2859f3a291570367cffeb08f47af94cf0ce9/try-macosx64/try_yosemite_r7_test-xpcshell-bm136-tests1-macosx-build678.txt.gz:

* It looks like the MOZHTTP2_PORT env var is empty, causing the tests to try to connect to "https://localhost:/". That looks like a different bug, but I think we should fail noisily instead of retrying and eventually timing out.

* `PushDB.update` returns undefined instead of throwing if a record doesn't exist, or the new record is invalid. I can't remember why it did that, but it's broken because callers don't null-check the result. This causes us to swallow rejections and print errors like '[JavaScript Error: "TypeError: record is undefined" {file: "resource://gre/modules/PushServiceHttp2.jsm" line: 667}]'.

* We don't observe 'serverURL' in tests, so there's lots of 'JavaScript Error: "Attempt to stop observing a preference "serverURL" that's not being observed" {file: "resource://gre/modules/Preferences.jsm" line: 323}' logspam.
