[bug] image isLoaded state was being set to false after it was set to true …

[sirugh]

Image isLoaded state was incorrectly being set to false. This PR removes the effect that was, for some reason, doing that. We don't need to set state to false on mount because that's the default state of the useState.

The reason this occurs on develop locally is that the images are loaded fast enough that the mount effect was happening after the load, which means we set isLoaded to true and then we trigger the effect which sets isLoaded to false.

This is definitely a bug and will be seen with a fast image server.

This is not just on the mount but for all cases when src changes. Makes sense because when src changes, image need to be re-fetched. But since we are not handling the fetch part, it is safe to remove this block of code.

Right! Thank you for that.

This might be the reason why images fail to load on smaller devices in case #1584.
