[Paraview] some tables cannot be located using paraview.simple python api

[pat marion]

Laurent sent me the data off list.  I took a look at it and determined the
problem is something that has already been corrected since the 3.8 release.
Here is the problem and how to fix it for those users with v3.8:

clip = Clip(...)
...code constructs representations and sets display properties...
clip.ClipType.Origin = [...]
clip.ClipType.Normal = [...]

What is happening is the clip filter is constructed, some properties are set
in the constructor, but the properties defining the clip plane are not set
until the end of the python script.  It is fixed by just moving the code to
just after the constructor:

clip = Clip(...)
clip.ClipType.Origin = [...]
clip.ClipType.Normal = [...]
...code constructs representations and sets display properties...

This issue will occur for the clip, cut, glyph, and possibly other filters.
It was fixed on April 30 with git commit d9119f6be4b10 and exists in the
release branch as well.
