Purpose
SchemaManager.generateTableSchemacan produce an invalid option combination after applying schema changes. For example, resettingfields.<seq>.sequence-groupmay leave a field-specificaggregate-functionthat requires that sequence group, and the failure is only exposed later when the table is loaded.Changes
TableSchemabefore returning it fromSchemaManager.generateTableSchema.fields.<field>.aggregate-function.last_non_null_valuebehavior unchanged, since it does not require a sequence group.Tests
