Subject: Fix serialization of delegates without targets
X-Git-Tag: accepted/tizen/base/20180629.140029~3804^2~1

Fix serialization of delegates without targets

A null check is missing when FEATURE_REMOTING is not defined, resulting in an invalid cast exception when deserializing a delegate without a target (e.g. a delegate for a static method).
