Hob: forget selected_recipes and selected_packages after users change the machine

The patch is to fix [Yocto #2255]. Now the logic is:

- If users change the machine, the image combo is empty for users to select.
- If users load the template, the image combo should set the value of
  selected_image specified in the template.
- After loading a template, if users change the machine, the selected_image
  specified in the template should be removed from the image combo because
  it is probably invalid for a new machine.
- If users customize the recipe/package list, and change the settings which
  causes reparsing, selected_recipes and selected_packages should be remembered.
- If users add more layers, selected_recipes and selected_packages should be
  remembered.
