register_pandas_dataframe crashes kernel when receiving dataframe with multiple columns with same name

My Synapse kernel crashed when I tried to register a dataset where the dataframe had multiple columns with the same name. I am not completely sure if this is the correct place to post this, but this is the best place I could find.

Minimum reproducible example:
```python
dataset = Dataset.Tabular.register_pandas_dataframe(
dataframe = pd.DataFrame([[1,2],[1,2]], columns=['a', 'a']),
target = datastore,
name = "bad_dataframe",
show_progress=True,
)
```
What I would expect:
To get some feedback about why it fails, and the kernel should not crash.

What I get:
```
Validating arguments.
Arguments validated.
Successfully obtained datastore reference and path.
Uploading file to managed-dataset/13e4b3c6-8730-4951-bde5-2d2bc6456e2d/
InternalError: Ipython kernel exits with code -11. Please restart your session.
```
