[rules-users] WorkingMemory deserializing problem.

[Edson Tirelli]

   Pedro,

   You need to use the same rulebase you used to create the working memory
to deserialize it, as well as use the latest version of 4.0.x branch. I
fixed this problem a few days ago.

    IMPORTANT: we made an effort on improving/fixing serialization and
dynamic rules use cases in 4.0.5. So, anyone using serialization and dynamic
rules should upgrade to 4.0.5 as soon as it is released.
