fix(cache): Add try-catch for connection errors when clearing cache

• fix(cache): Add try-catch for connection errors when clearing cache

Previous code had no error handling in the case of Redis service being unavailable, which made the cache less reliable. Additionally, there was no cleaing of the underlying in-memory cache for fallback data, which could result in data not being properly cleared.

requested review from @malowe and @gnugomez

LGTM although I might be losing something due to the horrendous diff that gitlab is showing due to the change of formatting. Maybe we could try to separate the re-formatting and the actual code change into separated commits, so that we can get a proper diff to look at.
