Asset hot reloading doesn't reload files that initially failed to load

## Bevy version

0.9.0

## What you did

Loaded a custom asset file that failed to load (syntax error in file), I then modified (fixed) the file.

## What went wrong

The asset did not hot reload.

## Additional information

If I call ```asset_server.load("my_asset.txt")``` every game loop, the asset loader will repeatedly try to load the file, when it should only do so after the file has been modified and hot reloaded.

I have provided some example code.

[test_hot_reload.zip](https://github.com/bevyengine/bevy/files/10569520/test_hot_reload.zip)

In the ```assets/test.txt``` file, change the value to ```ok``` for the asset loading to succeed and anything else to fail.
