e2e test cleanup

- fix a typo that was resulting in a test being a NOP, and
   add actual testing to it.

 - fix two Expects() with incorrectly-ordered actual/expects

 - remove leading whitespace from an It() test name

 - To(BeTrue()) is evil. Wherever possible, replace it with
   useful string or field checks. When not possible, use
   the annotation field to indicate what failed. I got
   carried away here, #sorrynotsorry

 - remove unused system-test code
