Formerly, using sudo() on a record had the effect of replacing the
current user with the superuser. But sometimes, knowing who the "real
user" was was necessary, so we needed to store it somewhere. This is
basically why the key `binary_field_real_user` was introduced in the
context: to keep track of who the user was before switching to sudo
mode.
Since 1e6c3bec2c, however, switching to
sudo mode no longer changes the current user; meaning that the
`binary_field_real_user` is no longer necessary.
This commit removes the remaining occurrences of the now useless
`binary_field_real_user` from the code.
