tst_QSharedPointer: add more tests for forward-declared payloads

It is not sufficient that QSharedPointer<ForwardDeclared>'s default ctor
and dtor compile. Copy/move assignment/construction and swapping should work, too.

Arguably, there are more functions that should compile with just a forward-declared
payload, but this is a start.
