onClose may not be called for eagely initialized instances if override happens

[shchuko]

Describe the bug
onClose may not be called for eagely initialized instances if override happens

To Reproduce

Run this code:

package org.example

import org.koin.core.context.GlobalContext.startKoin
import org.koin.core.context.stopKoin
import org.koin.dsl.module
import org.koin.dsl.onClose
import org.koin.java.KoinJavaComponent.getKoin


class MyClass(val name: String) {
    init {
        println("Initializing '$name', allocating resources")
    }

    fun cleanup() {
        println("Cleaning up '$name', releasing resources")
    }
}

fun main() {
    val overrideModule = module {
        single { MyClass("override") } onClose { it?.cleanup() }
    }

    val module = module {
        // eager initialization
        single(createdAtStart = true) { MyClass("original") } onClose { it?.cleanup() }
    }
    
    // override
    startKoin { modules(module, overrideModule) }

    val instance = getKoin().get<MyClass>()
    println("Accessing '${instance.name}'")

    stopKoin()
    println("Koin stopped")
}

See output:

Initializing 'original', allocating resources
Initializing 'override', allocating resources
Accessing 'override'
Cleaning up 'override', releasing resources
Koin stopped

Expected behavior
onClose is called for both 'original' and 'override' instances. (Cleaning up 'original', releasing resources is printed too)

Actual behavior
onClose is called only for 'override' instance, possible leak.

Koin module and version:
koin-core:4.0.0
