Fix "child is taken care of" test
Tried to fix REMOTE_HOST from Authorization header, closes #1

  I can't seem to reproduce this in Mojolicious 5.47, becuase it forces
  userinfo() to be set from the header and the other way around. This
  has also been around for quite some time, so I'm not sure why this is
  an issue.
