SMACK-458 Managers should be kept on disconnects

Browse source 
Smack's Managers should not remove itself when the connection is closed
or should re-add themselves if the connection get reconnected.

This should also fix some NPE's.

We are currently going with two different designs of Manager: 1. The one
with WeakReferences/WeakHashMaps (SDM, EntityCapsManager) and 2. the one
where the managers remove their listeners on connectionClosed() *and*
connectionClosedOnError(), and later add their listeners on
reconnectionSuccessful(). The first design has the Connection instance
only weak referenced. The other design does reference Connection
strongly (e.g. the 'managers' map in IBBManager/S5BManager), but removes
this references when connectionClosed(onError)() is called.
