Update summarization `run_pipeline_test`
# What does this PR do?

Update summarization `run_pipeline_test`.

A few more models can handle longer sequences, and won't give expected exception at this place
```python
            with self.assertRaises(Exception):
                outputs = summarizer("This " * 1000)
```
So we need to ignore those model config classes.
