Ignore missed AUX_FILES_KEY when generating image layer (#5660)

Browse Source 
## Problem

Logical replication requires new AUX_FILES_KEY which is definitely
absent in existed database.
We do not have function to check if key exists in our KV storage.
So I have to handle the error in `list_aux_files` method.
But this key is also included in key space range and accessed y
`create_image_layer` method.

## Summary of changes

Check if AUX_FILES_KEY  exists before including it in keyspace.
