[BUGFIX] Properly (un)serialize ReflectionService

The ReflectionService usually doesn't get serialized by users
directly but since Extbase has an unclean dependency chain, the
serialization of the ReflectionService is triggered in user land
code when serializing a LazyObjectStorage e.g.

Since it's no problem to implement a clean serialization and
unserialization of the ReflectionService it is implemented with
this patch and will no longer cause any troubles.

There is just one thing to mention. The ReflectionService usually
comes with a cache which cannot be restored during wakeup of the
serialized service. It's unlikely but it's possible that the
absense of the cache can cause a performance hit.
