support proper values for listMultipartUploads/listParts (#9970)

object KMS is configured with auto-encryption,
there were issues when using docker registry -
this has been left unnoticed for a while.

This PR fixes an issue with compatibility.

Additionally also fix the continuation-token implementation
infinite loop issue which was missed as part of #9939

Also fix the heal token to be generated as a client
facing value instead of what is remembered by the
server, this allows for the server to be stateless 
regarding the token's behavior.
