Ensure we can actually save an answer

Problem/Motivation

Since we've hidden the title field for answers, we can't save answers since Drupal is requiring the title field to be saved.

Proposed resolution

Check if we can either save it empty, or put a placeholder in it.

Remaining tasks

Do the change so we can save answers.
