vtkPVProgressHandler: avoid recursive errors
vtkPVProgressHandler could cause recursive error messages to be generated if the client connection dies. This avoids that.
With this change, I only get the following output:
./bin/pvserver
Invalid MIT-MAGIC-COOKIE-1 keyWaiting for client...
Connection URL: cs://miron:11111
