Crash fix for AvatarManager when iterating over _avatarHash

Browse source 
The main problem is that a null shared pointer was inserted into the _avatarHash
via the AvatarManager::getAvatarBySessionID().  When the sessionID is not present
in the _avatarHash, [QHash](http://doc.qt.io/qt-5/qhash.html#operator-5b-5d) will *insert*
an empty smart_ptr into the hash.
