Godot: Change type always says Node

[KoBeWi]

Godot version:
3.2

Issue description:
When you select Change Type in scene tree, you always see this

But the format for this string is Change %s Type. It's filled incorrectly.

[timothyqiu]

The %s part shows the base type of the available types. It shows "Node" when using scene tree's Change Type, and shows "Object" when using Visual Script editor's Change Base Type.

(It means something like: I want to change the type of this Node object from Label to AnimationPlayer.)

Maybe we could change the string so it says Change Node "MyLabel"'s type (if the node is named MyLabel). This would be more explicit.

@Calinou Sounds good. I'll start working on it.

@KoBeWi @timothyqiu @Calinou
void CreateDialog::popup_create(bool p_dont_clear, bool p_replace_mode, const String &p_select_type)
This function is called to create the dialog for changing the node. Looking at the parameters, would it not be better if the message is changed to Change Node MyNodeType or something like this?This way, the users can know the type of the node they are going to change without closing the dialog for checking.

I think convert is more suitable than change. i.e. Convert MyNode from "CurrentType"

@Janglee123 Much better. I'll make a PR for this.
