OpenFileCommandHandler doesn't check editorProviders.Length #277

If the application doesn't provide any IEditorProvider exports, then editorProviders will be an empty array. This leads to the Run() code trying to populate dialog.Filter with "All Supported Files||", which is not a valid Filter value and causes an argument exception to be thrown.
