[Paraview] TemporalParticlesToPathlines filter missing scalar

[Bill Sherman]

A followup to my question.

Presuming this is a bug, which means it might require some time to
fix, I went ahead and figured out a work-around.

I just bring up a "Calculator" filter and duplicate the problematic
field ("mass") as "massdup", and then put that through the
TemporalParticlesToPathlines filter.  And now I have access to
the data of interest.

Curiously, it's the "massdup" field that is now replaced by "TrailId".
