Development Settings: fix setting reset on disable

When Development Settings are disabled, some settings are
reset to values other than the default. This fixes it.

 - No need to have resetAdvancedReboot(), as it is already
   reset by the "unckeck all checkboxes" logic.

 - Adb notify should reset to enabled

 - Verify apps over usb should reset to enabled
