Add validate_table_existence to abstract SettingsManager (#5236)

The `BackendManager` was using the `validate_table_existence` from its `SettingsManager` member, but this method was not defined in the abstract class. It was present in both backends implementations, but there would be nothing requiring from the abstract parent class. Co-authored-by: Chris Sewell <[email protected]>
