iOS is the only platform that doesn't support Ti.Filesystem.File.parent property. We should ideally support it for parity's sake.

PR: https://github.com/appcelerator/titanium_mobile/pull/9285 Test-Case (additionally to the unit-test):

   var win = Ti.UI.createWindow({
     backgroundColor: '#fff'
   });
    
   var btn = Ti.UI.createButton({
     title: 'Log parent file path'
   });
    
   btn.addEventListener('click', function() {
     var file = Ti.Filesystem.getFile('app.js');
     
     Ti.API.warn('Native Path (File):');
     Ti.API.warn(file.nativePath); // Will return the file path
   
     Ti.API.warn('Getter (file.getParent()): Should return a (deprecated) String reference');
       
     Ti.API.warn(file.getParent()); // Will return the parent path
     
     Ti.API.warn('Property (file.parent): Should return a Ti.Filesystem.File reference');
   
     Ti.API.warn(file.parent); // Will print the path of the file because of the class-description
     Ti.API.warn(file.parent.nativePath); // Will return the paren path
     Ti.API.warn(file.parent.getNativePath()); // Will return the parent path
   
   });
    
   win.add(btn);
   win.open();
