WCS 2.0 rectified coverage scaleAxes bug

[pacesm]

There is a bug in the axis scaling part of the renderer:

Traceback (most recent call last):
  File "/usr/local/eoxserver/eoxserver/services/views.py", line 68, in ows
    result = handler.handle(request)
  File "/usr/local/eoxserver/eoxserver/services/ows/wcs/basehandlers.py", line 267, in handle
    result_set = renderer.render(params)

  File "/usr/local/eoxserver/eoxserver/services/mapserver/wcs/coverage_renderer.py", line 257, in <genexpr>
    for scale in scaleaxes
AttributeError: 'ScaleAxis' object has no attribute 'value'

The ScaleAxis has no value property. The scale property should be used instead.

Since all the tests are passing I assume a new test case covering the scaleAxes WCS requests should be added too.

The bug is fixed but the tests are still missing.
