RFR: 6664309: Docking point of a floating toolbar changes after closing [v2]

[Prasanta Sadhukhan]

> Issue is if we create a floating JToolBar at the EAST side and drag it and then if we close the floating toolbar, then it gets docket at NORTH side instead of the EAST side where it was docked before being floated.
> This is because of some contentious code in BasicToolBarUI where we change the constaint to NORTH if it is EAST/WEST.
> I could not find any JBS which did that code change.
> 
> Albeit, removing that piece of code does not cause regression in "clientlibs" jtreg/jck tests in addition to solve this anomaly, so thought, removing the code seems prudent..
