* refactor: parseUri types and checks
The type has been refined to better represent what it actually is. Uses of
parseUri are now also checking the parsed object type before resolving.
* cannot resolve URLs with fragments
* also take remaining part of URL into account
Needed for parsing the follows URIs.
* Resolver uses DbResolver for local
* remove unnecessary use of DbResolver
Using DbResolver would mean that the URL is parsed and handled again.
This duplicated processing can be avoided by querying the database directly.
* fix missing property name
