Running a Django app with auto-reloader prevents some functions from getting instrumented

To reproduce:

• clone https://github.com/redpointsec/vtm
• run the setup steps in its README, stop before running ./manage.py runserver
• pip install appmap
• ./manage.py runserver
• browse to http://localhost:8000/taskManager/dashboard/ (you'll have to log in first)
  The resulting AppMap looks like this:

• stop the server, start it again as ./manage.py runserver --noreload
• Browse to the dashboard, check out the resulting AppMap:

使用 vtm setup、./manage.py runserver 和 dashboard URL 重现该问题，然后使用 ./manage.py runserver --noreload 再次执行。比较生成的 AppMaps，以确定在 Django 的 auto-reloader 下缺少哪些函数。当重新加载配置产生的 instrumentation 与无重新加载运行时等效时，即表示完成。
