We now avoid the pre-computation of the base URI in PagedResourceAssemblerArgumentResolver as the actual assembler will fall back to using the URI of the current request by default anyway. The latter makes sure that request parameters, that are contained in the original requests appear in links created. If a controller wants to deviate from that behavior, they can create a dedicated link themselves and hand that to the assembler explicitly.
Fixes GH-2173, GH-452.
