RFR: 8203925: tools/javac/importscope/T8193717.java ran out of java heap [v2]

> Hi all,

> Because [JDK-8225054-PATCH](https://github.com/openjdk/jdk/commit/827e5e32264666639d36990edd5e7d0b7e7c78a9) modified `T8193717.java`, changing `private static final int CLASSES = 500000;` to `private static final int CLASSES = 50000;`(500K -> 50K). The error, `out of java heap`, no longer occurs now. And the pre-submit tests of this patch passed. I think `tools/javac/importscope/T8193717.java` could be removed from `ProblemList.txt`.
