[Paraview] Python interface: ExportView does not accept parameters

[Utkarsh Ayachit]

This is indeed a bug. I've reported it here [1]. Attached script shows
how to overcome this issue in 4.3. You'll need to add the following
stub to your code. Note this is only a workaround. Once the bug is
fixed, one should not use this hack.

# HACK: Overcomes a bug# 15298
conn = servermanager.ActiveConnection
misc = conn.Modules.misc
servermanager.createModule("exporters", misc)
