Nuke database on install and fix specification test Need to empty database as part of install_init(). Wasn't a problem for sqlite/anydbm as those got nuked by killing the test directory on each new test. For postgres/mysql in CI it needs to be nuked. Using admin.force=True to get the admin.py module to do it. If that doesn't work can open the instance and nuke it manually. Fields listed when getting specification for class are in different orders for different databases backends and versions. Use sorted lines for comparison.
