Editor crashes when "main.rs" is empty

[ruza-net]

When the "main.rs" file is saved empty, the whole editor freezes and shortly crashes. During the freeze, a really high spike in CPU usage occurs. The analyzer doesn't show the compilation error that no fn main() was found, so the issue likely occurs during this check.

The editor works normally when in safe mode (eg. all packages disabled).
