manage_user doesn't try to create a new user, but it doesn't handle
enrollments, so we have to enroll the users in a separate task using
another management command.

Additionally, it takes only password hashes, not passwords, so we have
to provide a pre-salted and pre-generated database string.

create_user used to autoconvert honor@example.com into honor for
username, we have to do that in the config now.

The headers were pointing to the old github wiki. Since we've officially
moved to Confluence, these links should be updated.

We updated code elsewhere so that by default courses that are
imported are imported into the split modules store but that also
changes the course_id of this course and breaks the enrolling of
test students into the demo course.  This change should resolve
the issue.
