Target setup page: Fix some glitches

- Make sure the "Manage" button is always enabled.
- Clear the list of possible build configs and collapse
  the details widget when a kit becomes unusable.
- Do not collapse the details widget when it gets selected.
- The "Details" button was sometimes grayed out when it shouldn't
  have been.
