Fix/remove nonexistent google drive test fixture (#553)

[`--extensions
"pdf,docx"`](5260411#diff-7e71fd57f028238499116faf502900d243db2496c78c7bc02079f0157a0ccaf7L54)
was removed from `test_e2e/src/google-drive.sh` which caused
`src_e2e_test` to start processing all files instead of just pdf and
docx files. As as result, the testing is failing because
`recalibrating-risk-report.pdf.json` doesn't exist in the [google
drive.](https://drive.google.com/drive/folders/1OQZ66OHBE30rNsNa7dweGLfRmXvkT_jr)
