When dealing with 'embedded' IDs (and the like, e.g. shape keys), liboverride code could fail in case the reference linked data (e.g. a mesh) would not have a shapekey anymore, while the override mesh would still have one. Found while investigating another issue in Heist production file `Heist/pro/animation_test/einar/einar_new_expression_shapes2.blend`, r1230.
