(core) port some more test/browser tests to newer selenium

Summary:
Ports more test/browser tests from *.test.js (run using an old selenium setup) to *.ntest.js (run using newer setup).

Weird test failures happened due to a change in timing. Eventually tracked in down to billing changes in one test suite resulting in reloads in another test suite, since it turns out redis pub/sub channels are not scoped to the redis database specified in REDIS_URL, but are global:

Test Plan: Ported tests should run and pass
