RFR 8179852: Remove references to demo tests from TEST.groups

[Alexandre (Shura) Iline]

Hi.

Can you please take a quick look on this fix.

Bug: https://bugs.openjdk.java.net/browse/JDK-8179852

Change:
$ hg diff
diff --git a/test/TEST.groups b/test/TEST.groups
--- a/test/TEST.groups
+++ b/test/TEST.groups
@@ -465,7 +465,6 @@
 needs_jdk = \

   com/sun/tools \
-  demo \
   jdk/security/jarsigner \
   sun/security/tools/jarsigner \
   sun/security/tools/policytool \
$ 

Notice that references to sample tests still exists but the tests themselves are listed in the ProblemList.txt

Thank you

Shura
