Bug: ENOENT when trying to load file that has been removed

[jp-performance]

When adding a file in the markdown that is saved in the /assets folder and the file is later on being removed (from the /assets folder as well as the reference within the markdown file), Obsidiosaurus runs into the following error:

Error: ENOENT: no such file or directory, copyfile '/Users/jp-performance/Desktop/wiki/vault/assets/example.svg' -> '/Users/jp-performance/Desktop/wiki/website/static/assets/example.svg'.

The markdown files itself are converted correctly.
After manually deleting the respective asset in the assetInfo.json, the conversion process finishes without throwing an error.
