Dangling mux.videoAsset documents remain when file uploads are not gracefully aborted

[robinpyon]

Steps to recreate

Either:

1. Initiate an upload (either manually with a local file or via copy and paste)
2. 'Ungracefully' abort the transaction (by navigating to another part of the studio, reloading the browser etc) before the file has completed uploading

At this point, the studio will have created a dangling and incomplete mux.videoAsset document with status === "waiting_for_upload".

I think Sanity's proxy is responsible creating this mux.videoAsset as part of its upload endpoint.

Perhaps the solve is deleting any associated mux.videoAsset where status !== ready || preparing when the Uploader component unmounts.

This is still an issue for me. Is this being worked on?
