fix(android): autoFocus causing crash on some versions of Android

[harnk]

• Refactor Ti.Media.takePicture auto-focus callback
• Prevent auto-focus related crashes on older Android verions

TEST CASE

const overlay = Ti.UI.createView({});
const takePicture = Ti.UI.createButton({ title: 'Take Picture' });

takePicture.addEventListener('click', _ => {
    Ti.Media.takePicture();
});
overlay.add(takePicture);

function showCamera(e) {
    Ti.Media.showCamera({
        success: e => {
            if (e.success) {
                console.log('Taken picture successfully!');
            } else {
                console.error(JSON.stringify(e, null, 2));
            }
        },
        saveToPhotoGallery: true,
        autohide: false,
        overlay: overlay,
        mediaTypes: [ Ti.Media.MEDIA_TYPE_PHOTO ]
    });
}

if (Ti.Meda.hasCameraPermissions()) {
    showCamera();
} else {
    Ti.Media.requestCameraPermissions(e => {
        if (e.success) {
            showCamera();
        }
    });
}
