PostgreSQL Fix in db_setup.sh restarts postgresql daemon in any case

[DePierre]

The fix for postgresql SSL configuration in the file db_setup.sh restarts the daemon even in the case when the user said "no" to the fix:

$ ./scripts/db_setup.sh init

Having SSL=true in postgres config causes many errors (psycopg2 problem)

https://github.com/owtf/owtf/blob/develop/scripts/db_setup.sh#L33 does not check the user input before restarting the daemon.

I would expect the script to do nothing if I answer "no", especially since restarting the daemon takes quite some time.
