-------------------------------------------
[~alapin], [[email protected]] I've found TODO refers to the resolved
ticket IGNITE-15414.
Seems, it was decided to replace per-table event listeners for schema changes
with a single listener for all schemas and provide a context for the change.
I've tried to rewrite the code using any() and faced onCreate() is called
multiple times with the same context.
Moreover, at some point, I see an empty _tablesById_ map that causes NPE.
Is it ok and I do smth wrong or there is a bug?
Please, run AbstractSchemaChangeTest in PR to reproduce.
