Misleading error when Autoloads appear in the wrong order (Native class "" not found.)

Issue description

If you have two AutoLoad scripts (A and B), and B references A, then B must appear after A in the "Autoloads" list. When this is not the case, the editor will give the following cryptic "Error", in the "Debugger" panel:

    Native class "" not found

I think it would be better to say something like:
"Class B references class A, but B appears before A in the Autoloads list"

Note that this is some kind of parsing error that occurs at runtime --even though the error appears, it is still possible for B to use A while the game is running. (Or maybe putting B before A is not actually even an error, and I've been doing too much C++ programming?) Regardless, the error message is very misleading.

Steps to reproduce

1. Open the sample project
2. Run "Main.tscn"; close it once the window opens
3. Look in "Debugger -> Errors" on the lower panel. You will see: "Native class "" not found"
4. Press "Clear" to clear all errors.
5. Now, go to "Project -> Project Settings", and in "Autoload", drag "GameData" so that it is after "MasterNode".
6. Re-run "Main.tscn"; close it once the window opens.
7. Look in "Debugger -> Errors" on the lower panel. You will see no errors.

Note that "GameData" references "MasterNode", so it should appear after that in the Autoload list.
