The SQLPanel is tracking toolbar queries. While probably helpful for understanding the impact of the tool, I'm not sure if we should be tracking them. It's not really related to the developer's app.

Steps to reproduce

Settings:

DEBUG_TOOLBAR_CONFIG = {
    "TOOLBAR_STORE_CLASS": "debug_toolbar.store.DatabaseStore",
}

1. Access the admin
2. View the SQL Panel
3. The first two lines should be related to debug_toolbar_historyentry
