Project: Apache Airflow
Issue Type: Bug
Components: cli, database
Affects Versions: 1.10.3
Reporter: Arsen Arutyunyan
`airflow initdb` crashes when there is a dag in dag folder that has owner set
to None. It crashes with the following error:
{code:java}

This command which sole role is to initialize metadata database lies on the
critical path of any Airflow deployment. Having bad dag in dag folder should
not lead to the failure of this command.
