fix: diff-gen - incorrect identification of renamed tokens

[mrcjhicks]

Description

diff-generator incorrectly identifies token renames due to an invalid uuid comparison. Both objects being compared should be first checked for valid uuids before comparing the uuids otherwise there can be a false positive when neither object has a uuid.
