Fix issue in Resolver

When resolving a path without leading slash against a base url without
trailing slash, the resulting url has a slash now.
Previously: http://abc.com => blog => http://abc.comblog
Now: http://abc.com => blog => http://abc.com/blog

Besides that also update linting to PSR-12, add a missing throws tag in
Url class docblock and update schemes and suffixes.
