  Previously, the overload candidates never got an DUChain Declaration
  associated, meaning we could not inspect the API documentation in-line
  from the code completion. The reason was that most of the time the
  hinted declaration is also a valid "normal" completion item, and thus
  was found a second time. The findDeclaration call then returned null
  for the second call, since we added the declaration to the exclusion
  set after the first call. Instead, use a separate set for overload
  candidates to fix this. Note that the expanded argument hint item
  is still not showing any documentation in-line... Apparently there's
  more to fix to get this done properly.
  While at it, also use the ArgumentHintItem for the situations where
  we (now) find a Declaration, to get proper current-argument
  Then fix the unit test to expect the default arguments. Though
  potentially this is clang-version dependent? Anyhow, this makes the
  test pass for me on my machine with libclang from LLVM 5.0.0.
