Debugger reports wrong error line

[KoBeWi]

Godot version:
3.0/3.1-dev

Issue description:
Godot sometimes highlights wrong line when error happens. It's always the previous non-empty line and probably has something to do with inline code blocks (e.g. single-line if with statement).

That's the isolated case I managed to reproduce the issue, but it might appear on other occasions too. Maybe.

In the given example, if you put any non-empty line (like another print etc.) between the if line and error line, debugger will show it correctly.

Minimal reproduction project:
TestProject.zip

Same here (3.2 dev, Windows 10 x64 / NVIDIA GeForce GTX 1060 6GB / Intel Core i7 4790K):

Still reproducible in the current master branch (41c8ec9).
