Gradle: USE_DEPEND doesn't apply on tests

The error "java.lang.ClassFormatError: Invalid Constant Pool entry Type 18" is a known issue caused by the fact the gradle uses outdated ant. It can be avoided by USE_DEPEND=false. However, this seems to work for build, but not for tests - we face this error in tests despite using the USE_DEPEND workaround.

Please make USE_DEPEND apply also on tests.
