Fix a padding setter bug of ol.View when using useGeographic()

[kikuchan]

Setting padding of View instance after creation corrupts center coordinates when using useGeographic().

useGeographic();
const view = new View({
  center: [135, 35],
  zoom: 6,
});

const center = view.getCenter();
// [ 135, 34.999999999999986 ]

view.padding = [0, 0, 0, 0];

const point = view.getCenter();
// [ 0.001212725633561354, 0.0003144103494321371 ]

This should be center == point roughly because there is no change about the padding.

This PR fixes the bug, and includes a test for it.
