* server: provider: last ResponseInfo container page serialization (#804)

fix: serialize ResponseInfo containers without a next page or members

OslcRdfOutputFormatter coerced a missing ResponseInfo next page to an empty
string and passed it to CreateDotNetRdfGraph, which then called new Uri(""),
throwing for every non-paged OSLC query response. Keep a missing next page as
null so no oslc:nextPage triple is emitted.

CreateDotNetRdfGraph also threw when building a ResponseInfo container for a
query that matched no members: EnsureNamespacePrefix relied on
INamespaceMapper.GetPrefix as a presence check, but it throws RdfException for
an unmapped URI, so the oslc prefix was never registered for an empty result.
Detect an already-mapped namespace without the throwing call.

Adds regression tests covering empty, null and present next page as well as
the empty-member container.
