Tentative fix for hanging questions on uninstall.

Contentscript now tries sending a message to the background page every
time the contentscript's page becomes visible. If the message fails, the
question is removed. Obviously, this is not a perfect solution which
fails for pages that are already visible (e.g. in another window), but
there's apparently no API uninstall event to hook to...

Refactor.

- Tentative fix for a failing focus on the answer field;
- Reduce nesting in message handler by using `return` instead of `else`
  blocks;

- Rename `resetAnswerElement` to a more semantic `setupAnswerElement`;
- Outsource anonymous new question initialization function to a named
  one;
