Updated python-django packages fix security vulnerabilities

User with hardcoded password created when running tests on Oracle When running tests with an Oracle database, Django creates a temporary database user. In older versions, if a password isn’t manually specified in the database settings TEST dictionary, a hardcoded password is used. This could allow an attacker with network access to the database server to connect. (CVE-2016-9013) DNS rebinding vulnerability when DEBUG=True Older versions of Django don’t validate the Host header against settings.ALLOWED_HOSTS when settings.DEBUG=True. This makes them vulnerable to a DNS rebinding attack. (CVE-2016-9014)
