LanguageManager should not call Destroy if Application.isEditor is true

[FlorianGlawogger]

LanguageManager Awake methode: only call Destroy in the Awake function if Application.isEditor is false, otherwise you can get a (harmless but annoying) error:

i.e. change

else if (Instance != this)
{
    Destroy(gameObject);
}

to

else if (Instance != this && !Application.isEditor)
{
    Destroy(gameObject);
}
