Summary:
In ContextContainer, only in Debug mode, we store type information alongside with data to detect typemismatch in runtime. We used type hashes before, but seems they are not so stable and can cause some false negative crashes.
This diff changes that to store mangled typenames instead of hashes, so it should be much more reliable now.

Summary: Sometimes we don't know for sure if `ContextContainer` has a value or not (and that's perfectly legit use case). In those cases now we can use `findInstance` method that returns an optional intead of throwing an exeption.
