Add support for scope linking in checkModules

[Pfoerd]

Enables "simulation" of linked scopes in checkModules. Thus, we don't have to explicitly provide default values for all of the injected instances coming from other scopes.

val myModule = module {
    scope(named("scope1")) {
        scoped { ComponentA() }
    }
    scope(named("scope2")) {
        scoped { ComponentB(get()) }
    }
}

scope2.linkTo(scope1)
scope2.get<ComponentB>()

@Test
fun `test DI modules`(){
    koinApplication {
        modules(myModule)
        checkModules(){
            withScopeLink(named("scope2"), named("scope1"))
        }
    }
}
