Fixed a bug regarding `commerce.hub.cache` properties

The deprecated commerce cache properties prefixed commerce.hub.cache caused application startup to fail. This bug has been fixed so that these properties can be used again. But still remember to convert them to cache.<capacites|timeout-seconds>.ecommerce properties soon.

Fixed suppression of gRPC exceptions and prevented empty cache objects in catalog service

In previous versions, all types of gRPC status exceptions in the catalog service were catched and only logged with debug messages. This lead to empty catalog objects being cached.

When catalog objects cannot be found now, no empty objects are cached anymore and and an info message is logged. All other exceptions are not catched.
