[PATCH v2 2/2] settings: Use explicit setup for the Debug Toolbar

[Stephen Finucane]

The 'django-debug-toolbar' application provides an automatic method of
configuring the plugin. However, as noted in the documentation [1],
this can cause issues like circular imports. In this case, a
"Table 'patchwork.patchwork_state' doesn't exist" exception was being
raised when attempting to do an initial migration.

Resolve this by using the manual configuration provided in the docs.
