For context, enable_feed_v1=false removes the v1 version of the NTP
feed from the build. This CL fixes various problems with that
configuration:

* fixed some tests
* fixed some unused resource errors
* some tests were more difficult to fix, i've made some
  assertions conditional. Instant start isn't yet implemented
  for v2, so it's likely these require more than test updates.
