Bind the local index to the s3.* destination too (closes #298)
The local index was bound to its destination only through storage_url.
With the s3.* form nothing was checked, so after s3.bucket or s3.prefix
changed the next backup treated every chunk as already stored, uploaded
nothing, and completed a snapshot that could not be restored.

Without storage_url, the binding now records the destination the s3.*
fields name, written as an s3:// URL from s3.endpoint, s3.bucket and
s3.prefix, and a change is refused with the same error and advice. The
advice line now names the s3.* fields as well as storage_url.

Judgement call: the fields are compared as written, so an equivalent
spelling (a trailing slash on the prefix, a scheme on the endpoint) is
also refused, as it already is for storage_url.
