RFR 8231508: Spec Clarification : KeyTab:exist() method does not specify about the fallback details

[Weijun Wang]

I added a CSR at https://bugs.openjdk.java.net/browse/JDK-8232994, please take a review.

My point is that not only it's useless but it also be misleading, so better remove than ignore.

Thanks,
Max
