get object child returning an object that is not a child

[t3du]

Hi, the Get Object Child is inconsistent with the Get Object Children. Because the Get Object Child for the same name object returns the object even though is not a child. The Get Object Children does not do that, it only returns the children.

https://github.com/armory3d/iron/blob/8bf6b8fbf80bef6f12183413d1c23e2b9ccdeb5b/Sources/iron/object/Object.hx#L111

If it is right this way then that is needed in the documentation. Otherwise we need to adjust the code. Because get children does not do that so its misleading.

i open this issue to further discuss the options.
