Getting Certificate errors when I run Airflow webserver in dev mode

[Sumit Maheshwari <su...@gmail.com>]

I always been running webserver in development mode only, but recently I
started to see missing certificates errors in dev mode. However this issue
doesn't occur in normal mode.

I am working on latest master.

*$python setup.py develop*
Finished processing dependencies for airflow==1.7.2.dev0

*$ airflow webserver -d*
