(core) port test/home tests

Summary:
This ports the useful parts of the test/home tests to test/nbrowser (a chunk of the DocMenu tests were already covered).

I ripped out a chunk of test/browser code that is now no longer used.

I made a few changes to unrelated tests that happened to fail.

Test Plan: ported tests
