When generating a 'default' manifest (where there wasn't any linked), manifest_url doesn't exist

[dmurph]

I don't think there is an explicit problem here, as when generating the default manifest, nothing that uses the manifest_url is actually used (we just create the start_url, id, and scope). But many places reference this url in the algorithms, and in this case it doesn't exist.

Ok... so we need to make it clear that when there is no link relationship, there's still the processed manifest that gets generated and applied. And that a user agent can also override the defaults.
