clang-format/java: Unbreak genenrics formatting after r299952.

https://reviews.llvm.org/rL299952 merged '>>>' tokens into a single
JavaRightLogicalShift token. This broke formatting of generics nested more than
two deep, e.g. Foo<Bar<Baz>>> because the '>>>' now weren't three '>' for
parseAngle().

Luckily, just deleting JavaRightLogicalShift fixes things without breaking the
test added in r299952, so do that.
