Several failures had snuck into the js-tests suite, with varying degrees of

awfulness. Most of these are just places where the code had been refactored or

changed without updating the tests correctly, or where code had been merged

that used the older API.
The major issue was in the reviewablePageViewTests.js file, where a failed

expectation result involved some objects with a circular reference. Jasmine was

attempting to print this, which caused an infinite recursion and corresponding

browser hang (or even crash). I've changed the expectation to be a bit more

specific, which works around this particular failure.

Ran js-tests.
