Crash when accessing a local file and permission is revoked

In airplane mode (so no network)

- Open a room
- Send an attachment (image from the gallery for instance) to the room. It won't be sent of course
- Kill the app
- Open the same room
- Long click of the pending event with the attachment
- Observe the crash:

```

- We should only use the local file to render in the bottom sheet and not the original file location.
