Breaking change with getAsYouType from v7.2.0 to v7.3.0

[BjornTheProgrammer]

Thank you for your library! I love using it, however I'm encountering an issue when using some users of my library due to a breaking change from v7.2.0 to v7.3.0. I've boiled down the issue to this simple reproduction.

This code when run on two different minor versions outputs radically different.

import { getAsYouType } from "awesome-phonenumber";

const ayt = getAsYouType( 'SE' );
ayt.addChar( '0' ); // -> '0'
ayt.addChar( '7' ); // -> '07'
console.log('number1:', ayt.getPhoneNumber());
ayt.addChar( '0' ); // -> '070'
ayt.addChar( '7' ); // -> '070 7'
ayt.addChar( '1' ); // -> '070 71'
ayt.addChar( '2' ); // -> '070 712'
ayt.addChar( '3' ); // -> '070 712 3'
ayt.addChar( '4' ); // -> '070 712 34'
ayt.addChar( '5' ); // -> '070 712 34 5'
ayt.addChar( '6' ); // -> '070 712 34 56'
ayt.removeChar( );  // -> '070 712 34 5'
ayt.addChar( '7' ); // -> '070 712 34 57'
console.log('number2:', ayt.getPhoneNumber());
