[Paraview] Script operations cause Paraview to crash after deleting server

[Olumide]

Hello -

I've written a script that loads several dozen legacy VTK files 
outputted by a simulation into Paraview for visual inspection. 
Naturally, whenever I rerun the simulation, the contents of the files in 
Paraview require updating; because manually deleting each file from the 
  pipeline browser would take too long, I decided to delete the 
"builtin" server and attempt to reimport the files by running my trusty 
script. Unfortunately, Paraview doesn't think this is a great idea, and 
it crashes. (Because of this, I've taken to quiting the whole 
application and relaunching it - just to reimport files.) Surely, there 
must be a better way ;-) .

What say you, O wise Paraview gurus :-) .

Failed to locate server for newly registered proxy ( "sources" ,

My script uses servermanager.sources.LegacyVTKFileReader() to import 
legacy file, creates a representation as suggested in the thread
