Bug in scheduler with blocked element

Fixing bug when scheduler was blocked and we want remove and add again
scheduled method

Example

We scheduled teget for example method update

void MyObject::update(float dt)
{
//Here CCScheduler::m_bUpdateHashLocked is set to true
//Also here scheduler for LeafAnimator::getInstance() is
paused!

CCDirector::sharedDirector()->getScheduler()->unscheduleUpdateForTarget(&LeafAnimator::getInstance()
);

CCDirector::sharedDirector()->getScheduler()->scheduleUpdateForTarget
(&LeafAnimator::getInstance(), INT_MAX, false );
//So when we want reschedule paused field isn't updated. Priority also
but this is in todo :)
}
