Title: Fixing zoom-slider issue with jumping Thumb

According to https://github.com/geoext/geoext2/issues/184 this is a fix for the problem with the jumping thumb when the config-option "aggressive" is enabled. A circle call of of the 2 event-handlers (zoomend and update) should not happen anymore.
