Steps to reproduce

Pre-Condtion

1. Multiple Instance of uppy uploader must be created.
2. uppy.use(GoldenRetriever, { serviceWorker: true }); serviceWorker must be used.

• Create instance for uploder class
• Upload large file
• When upload % is > 5 , Close the browser
• Now again open browser, Re- select file and check behavior
• Upload will start from 1%

- I debug and found that upload id get changed when we reelect file

Expected behavior

• Upload Should Be start from where it stopped.
• If we use uppy.use(GoldenRetriever, { serviceWorker: true });, In this case re-select option is not visible. if should be visible

Actual behavior

Currently when try to re-upload file it show below error.
