[+BUGFIX] Fix AOP Proxy Building
This fixes a regression introduced by I1987e582a195e8913b7c80fa26ceeb3bbd0319f6
but the code was also wrong before the regression, forgetting some cases.
This changeset verifies the behavior of the ReflectionService with a new
functional test and uses the correct output data of the ReflectionService
in the new test for the ProxyMethod.
Before this patch, annotations with no arguments were not
transferred to the proxy class.
