there is another scenario :
one process with one task，the task have 4 versions. so the table
t_ds_process_task_relation_log will have 4 record,
wich is :
and table t_ds_process_task_relation has one record :
in version 2.0.0 edit this process is ok, because ProcessService.genDagData
method read from t_ds_process_task_relation , but in 2.0.5
ProcessService.genDagData read from t_ds_process_task_relation_log , so when to
save the process there well be 4 record pass to ProcessService.transformTask
method, which will cause Duplicate key error. @caishunfeng
