RFR: 8233177: Remove testcase for JDK-8001470 as fix has been reverted [v3]

[Prasanta Sadhukhan]

> Existing regression test is failing because textfield height is not as per test's expectation..Seems like the indic character being tried to render is not being loaded (probably because of missing glyphs) leading to 0 preferredSpan from [BoxView](https://github.com/openjdk/jdk/blame/5a74c2a67ebcb47e51732f03c4be694bdf920469/src/java.desktop/share/classes/javax/swing/text/BoxView.java#L545-L552) which is superclass for `i18nFieldVIew`, the field view for Indic characters.
> Tried block character in the test which is now being loaded properly leading to correct height..
