I want to use Spy.calls.thisFor() in an upcoming change, but that

wasn't introduced until Jasmine 3.8.0. This change updates us to use

that.
I spent a while trying to get it so I could import Jasmine entirely from

node_modules the way  we do for most of our 3rdparty libs, but I

haven't been successful on that yet, so this just updates the bundled

copy.
This also exposed a case where we weren't properly using

await expectAsync, which meant that some expect calls were happening

after the test case completed.

Ran js-tests.
