Ignore errors when patching an object that was removed too quickly, during the handling cycle or inside of the handlers.

Issue : #139

Description

If a handler deletes the object being handled, Kopf will try to patch its status after the handler as usually, and will fail, since the object does not exist anymore.

The same happens if the object is deleted too quickly, while the handler is running.

Previously, this was prevented by always having a finalizer before any handling. Since #24, the finalizer is added only when there are non-optional delete handlers, and skipped otherwise. So, it is now possible that the object is deleted while we handling it.
