src: replace FromJust() with Check() when possible

FromJust() is often used not for its return value, but for its
side-effects. In these cases, Check() exists, and is more clear as to
the intent. From its comment:

  To be used, where the actual value of the Maybe is not needed, like
  Object::Set.
