Subject: [PATCH] [AIRFLOW-586] test_dag_v1 fails from 0 to 3 a.m.

dags/test_dag.py tries to set START_DATE to 3
hours before using
datetime.replace, but it doesn't support minus
value as argument.
So we have to use timedelta instead of simple
numeric subtraction.

Closes #1852 from sekikn/AIRFLOW-586
