Subject: [PATCH] fix(polling): remove unused variable and preserve
 lastModifiedTime on Drive API failure

- Remove unused `now` variable from Google Drive polling handler
- Preserve stored lastModifiedTime when Drive API pre-check fails
  (previously wrote undefined, disabling the optimization until the
  next successful Drive API call)
