8246195: ListViewSkin/Behavior: misbehavior on switching skin

[kleopatra]

Cleanup memory leaks and malicious side-effects (produced by eventhandlers and listeners that were not removed) when replacing a ListViewSkin.

The fix is to remove the listeners/handlers as needed. Added tests that failed before and pass after the fix.

It's part of the ongoing cleanup effort JDK-8241364.
