Bug (watcher): retry on files whose blob has yet not been found.

[SHAcollision]

If a /file and a /blob are uploaded to the homeserver concurrently, the File will finish faster than the Blob , therefore, there is a big change that Nexus watcher will process a /file event whose blob does not yet exists leading to:

https://nexus.staging.pubky.app/static/files/cf3eris488gmgcribc9diomexbyddsr98dm9ejbcsorfar3sttwo/0032S6VRC92BG net::ERR_CONTENT_LENGTH_MISMATCH 200 (OK)

Ideally, this /file event line should be left to try later using the new Retry Manager #247 @tipogi

File Retry Manager is not yet good handled because I would like to work on that when the file related PR (#255) is closed. Once it is merged, I will take a look that error 👍

or could we create the /file event in the front end, once the file is uploaded?
