Clicking on logs / instance details on the following dialog causes an exception:

```

ValueError: year 0 is out of range
```
This is because the execution_date in the query param of the url is empty i.e:

`http://localhost:50008/log?dag_id=test_logging&task_id=check_exception_to_sentry&execution_date=`
