[Paraview] unknown properties returned by ListProperties?

Many thanks Cory for your feedback. Not adding empty (None) properties did not
help
(http://github.com/romangrothausmann/ParaView_scripts/commit/d3af645dd1af2a).
Anyway, "ForceUseCache" has a vector of value 0 so it seems to me the actual
problem still is that ListProperties() returns properties that are not part of
the specific object that is calling ListProperties(). E.g. help(repr) does not
list a property called "ForceUseCache" but e.g. "Visibility"
So I decided to only restore the property "Visibility" for a start:
http://github.com/romangrothausmann/ParaView_scripts/commit/d1c63f2682e834e
Even though there is no error on execution any more, the resulting PVSM has only
the visibilities set for the last loaded PVSM, i.e. the setting of the
"Visibility" of representations loaded from former PVSMs did not have any effect.
Is there a need to call some kind of Update() to make the property setting have
any effect? I tried some rendering
(http://github.com/romangrothausmann/ParaView_scripts/commit/294ff85a0cc7a), but
that did not help either.
