fix(clickhouse): _sentry_span might be missing (#3096)

We started auto-enabling the ClickHouse integration in 2.0+. This led to it getting auto-enabled also for folks using ClickHouse with Django via `django-clickhouse-backend`, but it turns out that the integration doesn't work properly with `django-clickhouse-backend` and leads to `AttributeError: 'Connection' object has no attribute '_sentry_span'`.
