Handle Stream() errors consistently in restclient

We should be following the same rules for Stream() as the normal body
request flow.

Also add slightly more output on a server error - in the future we may
want to clean this up but it's potentially hiding bad responses.

Related to #32009 but isn't the fix (so far)
