code cleanup: move voices->width in LoadVoice()

It's probably unnecessary code and could be removed. However, it would
break tests. This is a temporary solution.

The solution is to do it once in VoiceReset() and then if the "formant"
keyword changes voice->width.

src/libespeak-ng/voices.c

 		n_replace_phonemes = 0;
 		LoadMbrolaTable(NULL, NULL, 0);
 	}
+
+// probably unnecessary, but removing this would break tests
+voice->width[0] = (voice->width[0] * 105)/100;
 }
 
 static void VoiceFormant(char *p)
 	if (width >= 0)
 		voice->width[formant] = (int)(width * 2.56001);
 	voice->freqadd[formant] = freqadd;
+
+	// probably unnecessary, but removing this would break tests
+	if (formant == 0)
+		voice->width[0] = (voice->width[0] * 105)/100;
 }
 
 static void PhonemeReplacement(char *p)
 		voice_languages[langix] = 0;
 	}
 
-	voice->width[0] = (voice->width[0] * 105)/100;
-
 	return voice;
