If some issues occur outside of our extension, we might not get a valid
uid inside of our hooks. We will therefore add additional checks and
prevent any further execution.

We use the cache clear hook to index pages whenever the cache was
cleared.
This makes it possible to cover some cases like changing content on a
page. But also if an integrator configures to clear additional pages.
This is limited as we can not handle cache tags at the moment.
