Loader and QObjectMethod::method_destroy() use deleteLater() on their objects, preventing timely cleanup of the compilation unit

Function trimComponentCache does not clean unloaded components' cache, old versions are loaded after change. Function clearComponentCache works.

Issue occurs with Loader with following qml js code.

loader.source = ""
Cache.trim() // Wrapper for  trimComponentCache
loader.source = componentUrl

Also it occurs with manually creating component

object.destroy()
// Here I tried asynchronously waiting time, calling gc() and setting object to undefined, nothing of that helped
Cache.trim()
var comp = Qt.createComponent(componentUrl, Component.PreferSynchronous)
object = comp.createObject()

I'm attaching minimal example with Loader, with two reload buttons, one clearComponentCache, other with trimComponentCache. First one works, second does not
