8282640: Create a test for JDK-4740761

[srmandal]

Create a test for JDK-4740761

The issue observed is in a JFrame with a JTextField and a JScrollPane which contains focused component. When the JScrollPane was
is removed from its parent, focus stays with the the scroller
of the removed JScrollPane, instead of moving to the TextField.

The test verifies the same - i.e. it verifies that the removal of the scrollpane moves the focus to the JTextField present in the JFrame.
This review is for migrating tests from a closed test suite to open.
