`dolt dump` only works when there are tables

On a brand new database with no tables, I can create a procedure, but I can't dump the results unless there's a table.
The same applies for events.
```sql
tmp/main> create procedure proc() begin select 1; end;
Query OK, 0 rows affected (0.01 sec)
tmp/main*> exit

james@Mac tmp % dolt diff
diff --dolt a/dolt_procedures b/dolt_procedures
added table
+CREATE TABLE `dolt_procedures` (
+ `name` varchar(1023) NOT NULL,
+ `create_stmt` varchar(8191),
+ `created_at` datetime(6),
+ `modified_at` datetime(6),
+ `sql_mode` varchar(1023),
+ PRIMARY KEY (`name`)
+) ENGINE=InnoDB DEFAULT CHARSET=utf8mb4 COLLATE=utf8mb4_0900_bin;

james@Mac tmp % dolt status
On branch main
Untracked tables:
(use "dolt add " to include in what will be committed)
new table: dolt_procedures
james@Mac tmp % dolt dump --file-name procedures.sql
No tables to export.
```

Start at the implementation of the `dolt dump` command and trace the check that reports “No tables to export.” Reproduce the case with a new database containing only a procedure or event, then verify that the dump includes those objects without requiring a regular table.
