  Updating ace, hoping this fixes that error that is coming through on prod.
  load the first bio_edition if one exists and none is specified. Otherwise, build a new one.
  Also adding required slug field to custom profile. Initializing slug to person.slug by default (if one exists).
  Removed validation for biography on bio_edition. Filling bio_edition title to user name by default. Removing some options for slugs. This should improve user experience. If we get to the point where we need more, we can add more back. Updating buweb
