PathNotFoundException: Cannot delete file

## 🐛 Bug Report

We are seeing tons of errros reported in debug mode and Crashlytics due to this library.

At this point i suspect a combination of using `staleDuration` and `macNrOfCacheObjects` may be the issue, but idk.

The error looks like this:
`PathNotFoundException: Cannot delete file, path = '/var/mobile/Containers/Data/Application/B93E8C32-B37A-4447-9506-DCE70BDE8978/Library/Caches/image_or_placeholder/ef157500-49af-11ef-bb4b-b9800cbce33d.jpg' (OS Error: No such file or directory, errno = 2)`

Although i think it only started happening once we specified shared `cache_key`.

### Expected behavior

That the library internally handles missing cache files etc gracefully?

### Reproduction steps

Not sure, as mentioned it may be due to invalid config.

### Configuration

**Version:** `^3.2.1`

**Platform:**
- [17.5.1] :iphone: iOS
- [?] :robot: Android
