AssetServer:: load_with_settings ignores the settings if file was already loaded with default settings

Example from this PR: https://github.com/bevyengine/bevy/pull/11109/files:

```rust
let image = asset_server.load("textures/house_tree_river.png");

let image_repeat = asset_server.load_with_settings(
"textures/house_tree_river_copy.png",
...
);
```

if we use the same file name, second image will ignore the settings (`ImageAddressMode` to be specific). Here we are using a workaround: providing a different file name.

Start at AssetServer::load_with_settings and compare it with the preceding asset_server.load call shown in the issue and PR #11109. Reproduce loading the same file first with default settings and then with ImageAddressMode settings; done means the second load honors its settings without requiring a different filename.
