FileUpload: onRemove does not correctly return the removed file if it has already been uploaded.

[alequisk]

Describe the bug

I was using the FileUpload component in advanced mode when I needed to create a custom method to remove files from the database. I noticed that when trying to remove an already uploaded file, it returned undefined for the "file" key.

Analyzing the component, I found that the method responsible for removing an uploaded file mistakenly selects the array of files that are yet to be uploaded.

Same issue here, file is always undefined for files in the completed status; pending files are working fine. I'm using version "primereact": "^10.9.7".
