   If like this dag_run data is in airflow database, the toppage would be crush.
   
   ```
   mysql> select execution_date, start_date from dag_run where dag_id = '_masked__' order by execution_date desc limit 1;
   
   +----------------------------+------------+
   | execution_date             | start_date |
   +----------------------------+------------+
   | 2017-04-03 18:00:00.000000 | NULL       |
   +----------------------------+------------+
   1 row in set (0.05 sec)
   ```
   
   When I upgrade airflow to 1.10.2 from 1.8.1, the toppage doesn't work.
   It's caused the code in webserver doesn't check start_date.
   I think we need to add a check for start_date.
