Core: fix minor voicepack selection issues

- If the chosen voice pack is deleted/disabled, GUI shows it as a special missing entry. Selecting it caused an error comparing nil to number.
- If the chosen voice pack is deleted/disabled, voice was disabled (voiceSessionDisabled = true) until reload. Restore/re-disable when updating voice pack choice.
