Prefix key containing space throws S3Error with 403 SignatureDoesNotMatch response

[lionel-rowe]

Running the following:

await bucket.listObjects({ prefix: 'Project/contains%20space/', delimiter: '/' })

Throws Uncaught (in promise) S3Error: Failed to get object: 403 Forbidden. The XML response (edited slightly) is as follows:

<?xml version='1.0' encoding='utf-8' ?>
