Fix row slicing issue in UtilitiesClient

[jboliv01]

Description

During streaming uploads using the stream_upload function in UtilitiesClient, the DataFrame slicing was inadvertently causing truncation of rows. This was due to an extraneous comma in the DataFrame slicing logic.

Steps to Reproduce

1. Use a large DataFrame with the stream_upload function.
2. Observe that not all rows are uploaded as expected.

Fix

Removed the extraneous comma in the DataFrame slicing logic in the stream_upload function to ensure correct slicing of rows.

Testing

I've tested the fix with several large DataFrames and confirmed that all rows are now correctly uploaded.

Additional Notes

This fix ensures that data integrity is maintained during the streaming upload process.

@jboliv01 I was not able to reproduce this bug. Could you add a test that reproduces it?

[jboliv01]

Hi @samrands I've added a script you can use to reproduce the issue. Please let me know if you have any questions.

@jboliv01 I ran that test and the datasource using the old method was identical to the one using the new method. However, we'll still make this change because removing the comma fixes your issue and is more in line with the expected usage of the method from the documentation.

@jboliv01 We've been unable to reproduce the error even with your test. However, we also don't see any new issues. I'm going to go ahead and merge the fix in as it seems to fix the error on your side. If you have any further issues, let us know.
