[HOTFIX] fix tests for #308

[dataders]

Description & motivation

#308 introduced two issues that weren't caught until after merge:

• ignore_case was always used for the infer_schema pre-fetch even if it wasn't defined
• the integration test didn't correctly test the functionality

accordingly I:

• made ignore_case true by default (thanks @robby-rob-slalom!)
• created and uploaded the the S3 bucket a new set of parquet files (Jupyter notebook included)
• updated the tests

Checklist

• I have verified that these changes work locally
• I have updated the README.md (if applicable)
• I have added an integration test for my fix/feature (if applicable)
