Subject: [PATCH] CB-11838 ios: Unregister callback function at the right
 timing.

We at LINE observed about 40K crashes a day that were suspected to be
caused by the reacahability callback function invoked on an
already-deallocated object. We couldn't reproduced the crash locally
but this patch did reduce the number of crash reports to zero.

 This closes #49
