Clicking on a student's submission in the All Submissions page, during a test, shows stale data

[blerner]

Student submissions get updated every few seconds, during an exam. But graphql isn't informed that its data store is stale. The link to the student submission, in app/packs/components/workflows/professor/exams/submissions/index.tsx, probably ought to open in a new tab so as not to be accidentally stale.
