BUG #13571. Fix python issue with binaries.

The problem is possibly due to the Python Qt Testing framework incorrectly
initializing Python. Overcome the issue by deferring the Qt Testing python
initialization until needed. This will give ParaView the opportunity to init
python properly. Hopefully, this will address the issue.

Cleanup logic to locate pvserver.

The logic was a bit convoluted. Also reducing the timeout spent waiting for
pvserver to launch. 100s was excruciating.
