JUnit4 assumptions fail the tests when coming from setup() method of a super spec

Issue description

JUnit4 assumptions fail the tests when coming from setup() method of a super spec.
When debugging, it looks like the MethodInfo of the setup method does not have any interceptors in the failing case. Specifically, the ExceptionAdapterInterceptor that handles this case in the working case is missing.

How to reproduce

Repository with minimal reproducer: https://github.com/rieske/spock-junit4-assumptions-reproducer

Assumptions are handled correctly when this spec is executed:

class SuperSpec extends Specification {
    def setup() {
        assumeTrue(false)
    }

    def "super feature"() {
        expect:
        true
    }
}

Assumptions from super spec's setup() method fail as errors when this one is executed:

class SubSpec extends SuperSpec {
    def "sub feature"() {
        expect:
        true
    }
}
