Tests fail with SQLite 3.26+

See https://code.djangoproject.com/ticket/29182

Hopefully this will get fixed with Django 2.2.

Test fails with error like (note table name may vary):

django.db.utils.OperationalError: Problem installing fixtures: no such table: institute__old

Mysql and postgresql support are fine.

This is fixed now we have moved to Django 2.2
