…s not being re-scheduled when the client being shutdown. Failing to do so causes the shutdown to hang up. Possible scenario for generating the problem: 1. Trigger client shutdown. 2. The backup timer expired and its lambda code is being executed. 3. The connection close cancels the timer but it is not effective since the time is not in the wait queue. 4. The timer is being rescheduled. Also, checked all the other timers, they all have similar checks. Changed the location of the check for the `ClientConnectionManagerImpl::schedule_connect_to_all_members` method. fixes hazelcast#900
