Cleaned up ArtifactValidatorExecuter and IArtifactValidatorExecutor

This commit intends to clean the tests related to ArtifactValidatorExecuter and IArtifactValidatorExecutor by introducing the concept of test contract. Some renaming have to be done to fix the typo in Executer (it should be named Executor), hence the number of changes.
