If the scalar coord passed to iris.util.new_axis is already a dimension coordinate, an anonymous new dimension is created.

How To Reproduce

import iris
import iris.cube

print(iris.__version__)

cube = iris.cube.Cube(1)
coord = iris.coords.DimCoord(1, long_name="spam")
cube.add_aux_coord(coord)

When saving a pixel resolution with a decimal number (0.86 for example), the value is propagated properly.
However, on the next start, the value is not restored properly. It could be linked to the value being saved with a comma instead of a decimal point, as there is a need to replace the comma that appeared.
