Machines resize tests failing on COAL

On my COAL instance, the dimensions are insufficient to pass a particular test:

The test is expected to fail due to server dimensions, except that in this case it's failing across two dimensions, not the expected one. In this case:

{ code: 'ValidationFailed',
  message: 'Invalid VM update parameters',
  errors:
   [ { field: 'ram',
       code: 'InsufficientCapacity',
       message: 'Required additional RAM (10239744) exceeds the server\'s available RAM (-34953)' },
     { field: 'quota',
       code: 'InsufficientCapacity',
       message: 'Required additional disk (99990) exceeds the server\'s available disk (-1015)' } ] }

The quota error is expected. The RAM is not. It should handle the latter case gracefully too.

Start with test/machines/resize.js, especially the assertion at line 45, and run the machines resize test on a COAL instance. Check how the test handles the ValidationFailed response when both RAM and quota report InsufficientCapacity; done means the expected quota limitation and the additional RAM limitation are handled without an unexpected test failure.
