How to disable TTS instance in Here?

[ouafae31]

Describe the bug
We have a language not supported by Here voice catalog, so we fall back to Android Text to Speech. The issue is that if we have already initialised Here engine with a different language, we here them both when we start the map navigation.

Steps To Reproduce
Steps to reproduce the behavior:

1. Start map navigation in English
2. Change language to Romanian
3. Start map navigation and you hear English and then Romanian

Expected behavior
Hear navigation in Romanian only.
We tried NavigationMAnager.stop() NavigationManager.audio.stop
delete the catalog..nothing worked to not use Here tts instance in that case.
