Title: Alex/fix is completed

This all about is_completed function.

It was intended to be used in conditional in 8.02x, but had not been used at all. It is not used in Harvard justice too.

This pull request adds is_correct support to conditional and adds docstring to is_completed, to avoid misunderstanding of is_completed role.

@dianakhuang @shnayder @ichuang please review!
