The purposes of this test:
1. Show that our `PP` works
2. Show that it fix an issue of SPR `PP` - the `testBean` from `TestConfiguration`
3. The reason to place it in the separate `component2` just because our scanner see `IntegrationConfigurationContextConfiguration` from this class and we end up with issue in other tests from `component`, when `logger` bean tries to be registered twice.
4. If we change our `PP` to just SPR `PP`, there won't be `testBean` and the `getBeanCount` will be `0`
