This is apparently a regression of MDL-43670, where some quiz_question_instances columns were renamed.
Trying to restore the attached course backup (2.0 one), the process dies with error:
Error reading from database

It's seems that some ocurrence of the old names is still there.
Reproduction note: In order to reproduce the error, the attached backup file must be restored skipping the "One Quiz" activity completely (it contains some qtypes not present in 2.7 leading to error, unrelated with this issue).
