Overrides the default test database name so that multiple instances of Django parallel tests using the same database instance do not clash e.g. when testing multiple branches at once (like Bamboo's plan branches). Run using: `python manage.py test --testrunner='<path>.<to>.<class>.ParallelTestRunner' --parallel=<num_parallel_processes>`
