Download instead of updating href

[yamila-fraiman]

When using allowDownloadByUrl it changes current href instead of downloading a file. It should use same code as the Else content but instead of createObjectURL, use the metadata.

const downloadFile = (item, allowDownloadByUrl) => {
const a = document.createElement('a');
const url = allowDownloadByUrl && item.getMetadata('url') ? item.getMetadata('url') : window.URL.createObjectURL(item.file);
document.body.appendChild(a);
a.style.display = 'none';
a.href = url;
a.download = item.file.name;
a.click();
window.URL.revokeObjectURL(url);
a.remove();
};
