Stix1D won't compile because ComplexVectorCoefficientByAttr is not a trivial type

[cjvogl]

The line with the issue is https://github.com/RF-SciDAC/mfem/blob/plasma-dev/miniapps/plasma/stix1d.cpp#L905, which tries to construct an object of type Array<ComplexVectorCoefficientByAttr> which then trips a static assert within the Array class on https://github.com/RF-SciDAC/mfem/blob/plasma-dev/general/array.hpp#L57.

Relevant compiler error is
