Fix Failing/Passing SplineInterpolation test about datatransferkit

[sslattery]

valgrind seems pretty clean. I don't see any invalid reads or writes. messing around with the thyra operators gives some weird results. Maybe thyra wrappers for tpetra were not appropriately updated?

verified that on apply the target vector is being overwritten with zeros

After some work on this it is still not clear what the issue is. Although they involve a global linear solve at every apply of the operator, the splines are desirable because they are less sensitive to the choice of support radius. Still looking into this.

It was identified that a bug in Tpetra caused this. Depending on the Trilinos version, using beta=0 for a matrix vector multiply (the default) caused the vector to be filled with zeros. The current 11.14 patch tarball passes in release and fails in debug while the current state of the public repository passes for both. Since this is passing using the current state of Trilinos, this is fixed.
