Consider default SERVER_MODE =True for pgadmin4-v1-web

It would be nice if the pgadmin40v1-web package set the SERVER_MODE  = True

I can't think why you would install the web package without this but there may be a reason?
Also since the setup script does different things depending on this value if you don't do it first you have to delete
theconfig and sqllite database and start again otherwise it will never work 

Currently I have this in my setup script

#Overide SERVER_MODE (must be done BEFORE setup)
cat >> /usr/lib/python2.7/site-packages/pgadmin4-web/config_local.py << "EOF"
SERVER_MODE = True
EOF

Thanks
