Updating library version of a pasted library_content component loses learner state

[kdmccormick]

Reproduction

• In Studio:
  • Create a library ("libX") and add a problem to it.
  • Within a course unit, create a Library Content component ("LC1") and point it at libX.
  • Go to libX and make an edit. For example, you could change the question prompt slightly.
  • Go back to the unit with LC1. It should prompt you to "Update Now". Don't update.
  • Copy LC1 and paste it into the same unit (creating "LC2"). It should also prompt you to "Update Now". Don't update.
  • Publish the unit.
• In LMS:
  • Go to LC1. Submit the correct answer.
  • Go to LC2. Submit the correct answer.
• In Studio:
  • Go to the unit with LC1 and LC2.
  • Hit "Update Now" on both LC1 and LC2.
  • Publish the unit.
• Back in LMS:
  • Go to LC1. Your correct answer should still be submitted.
  • Go to LC2.
    • Expected: Your correct answer should still be submitted.
    • Actual: The problem is unanswered. Your learner state has been lost.

Note: Braden's PR will fix this going forward, but any copy/pasted library_content components that have been made in the meantime will lose learner state if ever updated.
