Revert "Fix unresolved external symbol vtkPVInitializePythonModules"
This dependency creates a cycle in the build graph. Additionally, there
is no reference to the vtkPVInitializePythonModules
in this module, so
it is the wrong place to add the link anyways.
This reverts commit a2364966 (!6375 (merged)).
