Skin does not update

[Kiryu144]

I'm currently trying to add a new entity, which looks like a smaller version of the player. It all works fine and dandy, except I want the mini-player to fetch the skin of its username.

Using the MojangAPI, I fetch the skin url and then use the following code:

ResourceLocation resourceLocation = new ResourceLocation("skin/" + uuid);

File file = new File("cacheXXX");
Texture texture = new DownloadingTexture(file, skinURL, resourceLocation, true, () -> {
    System.out.println("test");
});
texture.loadTexture(Minecraft.getInstance().getResourceManager());
Minecraft.getInstance().getTextureManager().loadTexture(resourceLocation, texture);
return resourceLocation;

I hope that properly binds the skin texture to the resourcelocation. 

Now using `getEntityTexture` in the renderer, I give it the new skin location. I know that works, because I set the skin to `DefaultPlayerSkin.getDefaultSkinLegacy();` on initialization, before overwriting the variable with the one returned from the top function.

The only thing that I could imagine is, that the renderer caches the first resourcelocation returned by `getEntityTexture` and not checks it again. I hope that makes sense!
