spec: fix newly embrittled spec
spec: fix newly embrittled spec

i think there may still be a bit of broken stuff here, but at least this
returns the spec to its previous passing behavior (more or less)

problems probably worth investigating:
1. student view quiz submissions result in `TypeError: submissionHistory
   is null` js errors (the problem we're working around here)
2. student view quiz submissions on a non-quiz result in a 500 in the
   submission pane. that may not even be a valid thing/supported, but it's
   what the spec does now (and did before the refactor that broke it)
