If tickless idle mode is in use then ensure prvResetNextTaskUnblockTime() is called after a task is unblocked due to a bit being set in an event group.  This allows the MCU to re-enter sleep mode at the earliest possible time (rather than waiting until the timeout that would occur had the task not being unblocked be the event group) and matches a similar change made for queues and derivative objects (semaphores, etc.) some time ago.
