SpringMockTestExecutionListener initializes @Lazy beans

[jiallombardo]

Issue description

Beans marked as @lazy are inadvertedly initialized when running spock-spring tests. I suspect the culprit is SpringMockTestExecutionListener:54. @lazy autowiring works fine, however, classes and @beans, annotated with @lazy, are loaded due to the invocation of applicationContext.getBean(...)

How to reproduce

I've uploaded a small project that has this issue reproduced in tests:
https://github.com/jiallombardo/test-spock-spring

When running LazyBeanInitializedSpec, you will notice an "I AM INITIALIZED" message in console log.
When running LazyBeanNotInitializedSpec (which is a regular, non spring spock test), this message won't appear.

Just a test which is expected to pass as per Spring semantics

@ContextConfiguration(classes = SpringConfig)
class SpringSpockSpec extends Specification {
    @Autowired
    Foo foo

    def "foo#bar shouldn't be initialized"() {
        expect:
        foo.bar == null
    }
}

@Configuration
class SpringConfig {
    @Bean
    Foo foo() {
        new Foo()
    }

    @Lazy
    @Bean
    Object bar(Foo foo) {
        foo.bar = new Object()
        foo.bar
    }
}

class Foo {
    Object bar
}
