Fix video assets not showing in composer

[nuno-vieira]

🔗 Issue Link

Regression introduced here: #767

🎯 Goal

I did not realise that onImageTap was also for video assets. So it was also trying to convert videos into jpg. So it broke the composer.

🧪 Testing

It should be possible to add video assets to the composer.
