Fix finding the correct login sessions in Velocity

Velocity uses different objects during each login phase.
Therefore, keys are no persistent. Only an internal variable
is shared and exposed with `getConnection()`, but this method
is not available in the API. We use `InetSocketAddress` objects
until there is a better method for identifying sessions.
