"kpm wrap" should automatically wrap dependency assemblies of an assembly if they are in the same dir

[ChengTian]

In current kpm wrap, if ProjectA.csproj references AssemblyB.dll and AssemblyC.dll is a dependency of AssemblyB.dll.

When kpm wrap ProjectA.csproj, although it also automatically wraps AssemblyB.dll, AssemblyC.dll is not automatically wrapped even it's in the same dir as AssemblyB.dll.
