Null pointer exception and failed to capture incremental snapshot for newly added table in Postgres CDC Source Connector

## Bug report

**What Debezium connector do you use and what version?**

`3.0.8`

---

**What is the connector configuration?**

Standard postgres configs, some configs to highlight

```
"database.dbname": "test_database",
"publication.autocreate.mode": "filtered",
"publication.name": "d1234",
"signal.data.collection": "public.debezium_signal_table",
"table.include.list": "public.*"
```
---
**What is the captured database version and mode of deployment?**

Both onprem and on cloud

---

**What behavior do you expect?**

Initially, postgres database had 2 tables, 1 signal table `debezium_signal_table` and one `normal_table_1`
Connector was started with above configs.
Then, a new table `normal_table_2` was created which matched regex, and few sample rows were added , and table was manually added to publication via ALTER publication. Then incremental snapshot was executed via entry in signal table as
```
INSERT INTO debezium_signal_table (id, type, data)
VALUES (
'adhoc-snap-002', -- unique id
'execute-snapshot', -- type must be 'execute-snapshot'
'{"data-collections": ["public.normal_table_2"], "type": "incremental"}' -- JSON data
);
```

The connector should capture the snapshot of `normal_table_2`.

---

**What behavior do you see?**

When we inserted in signal table above, the connector didn't captured incremental snapshot, and we got following error in log:

**Do you see the same behaviour using the latest released Debezium version?**

Code flow is same in latest main branch, so should exists.

---

**Do you have the connector logs, ideally from start till finish?**

Have pasted the relevant log above, if needed, will share detailed log.

---

**How to reproduce the issue using our [tutorial](https://github.com/debezium/debezium-examples/tree/main/tutorial) deployment?**

Have described above
