[SPARK-50489][SQL][PYTHON] Fix self-join after applyInArrow

### What changes were proposed in this pull request?
Fix self-join after `applyInArrow`, the same issue of `applyInPandas` was fixed in #31429

### Why are the changes needed?
bug fix

before:
```
In [1]: import pyarrow as pa

In [2]: df = spark.createDataFrame([(1, 1)], ("k", "v"))

In [3]: def arrow_func(key, table):
   ...:     return pa.Table.from_pydict({"x": [2], "y": [2]})
   ...:

In [4]: df2 = df.groupby("k").applyInArrow(arrow_func, schema="x long, y long")

In [5]: df2.show()
