Fixed the bug causing: `TypeError: generate() got multiple values for
keyword argument 'stop_sequences'`
```python
res = await self.async_client.generate(
prompt,
**self._default_params,
stop_sequences=stop,
**kwargs,
)
```
The above throws an error because stop_sequences is in also in the
self._default_params.
