Older recordings are not playable after configuring external storage (session not found error)

[Eyesonly88]

Describe the issue
If you have recordings that were stored locally using minio and then you configure external storage, then the older recordings are not playable anymore.

Steps to reproduce the issue

1. Have local storage configured and create some recordings
2. Play those recordings in the dashboard to confirm they were stored
3. Configure external storage such as Cloudflare R2
4. Try to play the old recordings
5. You get error session not found (check your retention policy)
6. Inspect the network with devtools and you will see it is trying to download the recording from external storage (which would not exist since it was stored locally before the external storage was configured)

Expected behavior
Old recordings that were stored locally continue to work as they are still stored on disk.
