The validateSourceSets task are created only for the test tasks. [check source](https://github.com/openjdk/jfx/blob/eb7de72dafecbedc83c2215b6aed7432d4ec80f9/build.gradle#L1848) So, validateSourceSets task must be executed when running test tasks even when TEST_ONLY=true. This had caused a regression [JDK-8310654](https://bugs.openjdk.org/browse/JDK-8310654), where we missed a failing scenario as validateSourceSets did not run with -PTEST_ONLY=true
