[jfx20] RFR: 8301797: Pagination control has the wrong size [v2]

[Andy Goryachev]

> Fixed regression introduced by JDK-8295754, targeting upstream **jfx20 branch**.
> 
> The method PaginationSkin.resetIndexes(true) has been moved to the original position in the constructor, fixing the initialization, while making sure no properties of the control are touched in the constructor (only in install()).
> 
> Added a test case.
> 
> Tested with the PaginationDisappear.java and the LeakTest app
> https://github.com/andy-goryachev-oracle/Test/blob/main/src/goryachev/apps/LeakTestApp.java
