Description

We should cleanup statements cache whenever cache is deregistered - otherwise it's possible to retrieve from statements cache a statement that is prepared from H2 perspective but may not be executed. Such situation may arise for any dynamic cache, not only for that created via SQL.
Reproducer attached.
