This commit bumps the following uppy modules:
* @uppy/aws-s3
* @uppy/aws-s3-multipart
* @uppy/core
* @uppy/drop-target
* @uppy/xhr-upload
This is done so we can use the new functionality for retrying
failed prepareUploadParts calls, introduced in
e435f4a917.
I also needed to make some changes to composer-upload-uppy to
support this retrying, while at the same time being able to
throw a bootbox with the error message if the number of retries
are exceeded.
