Ineffective scaling detection events are misleading

When the ineffective scaling decision feature is turned off, events are regenerated which look like this:

Skipping further scale up after ineffective previous scale up for 65c763af14a952c064c400d516c25529

This is misleading because no action will be taken. It is fair to inform users about ineffective scale up even when the feature is disabled but a different message should be printed to convey that no action will be taken.
