Fixes #154

Fix issue #154 

The error is caused by a change of logic in the json files: this script expects an empty field for `pseudocode score` when there is no pseudocode.
See warnings in error log: https://github.com/GraphicsReplicability/replicability.graphics/runs/898876115?check_suite_focus=true#step:3:761

Fix: Check only the pseudocode state when pseudocode is available.
