Service crashes when webapp requests a recording that doesn't exist

[MrFabio]

In the webapp, if we open a recent call and that call doesn't have a recording in the bucket (due to a api-server update, the old calls don't have a recording yet), the api-server crashes with the following log (and a few seconds later I'm logged out of the webapp):

ApiError: No such object: my-bucket-recordings/2023/08/01/abcd5559-aaaa-1111-a12e-9a0f48fce600.mp3

With the google bucket vendor and using api-server 0.8.4-4

If the recording doesn't exist, perhaps don't show the waveform.
