Description

When trying to send a push message to a user who has already destroyed his web socket connection, PushContextImpl.send throws NPE

java.lang.NullPointerException: Cannot invoke "java.util.Set.size()" because "channelTokenSet" is null
    at org.apache.myfaces.push.cdi.PushContextImpl.send(PushContextImpl.java:134)
    at org.apache.myfaces.push.cdi.PushContextImpl.send(PushContextImpl.java:122)

Method should be null safe, just to continue with next user identification.
