Fix Learning Mastery Outcomes text-wrap

Fixes: CNVS-25394

Test plan:

- This bug affects both Firefox and IE Edge on
  Windows 10
- Follow the instructions in the JIRA to create
  an Outcome and view it in the Learning Mastery
  Gradebook. Make sure the description is really
  long.
- Ensure the description is being truncated by
  ellipses after one line and that the layout is
  no longer being blown out (see the JIRA ticket for
  screenshot of bug). The page should now look like
  this: http://screencast.com/t/b5Jt5RZO
