Summary

This PR fixed the bug reported in #1208. In preprocess_propulsion(), all the Aircraft.Nacelle variables were assumed to allow multi-value. But Aircraft.Nacelle.TOTAL_WETTED_AREA is an exception. See _get_engine_variables() for details. The fix is to exclude it.

Two other scalar nacelle variables are Aircraft.Nacelle.DRAG_FACTOR and Aircraft.Nacelle.PYLON_DRAG_FACTOR. They are excluded too.
