Field mismatch error is only reported on the first compilation in vscode

[yuxiaomao]

Repro:

• Open in vscode and compile (probably some display/diagnostic requests are automatically sent), observe that only the first compilation shows missing field error (expected), the following compilations succeed and result in runtime null access.

class Foo {
}

class Main {
	static function main() {
		Foo.bar();
	}
}

Remove && Common.is_compilation com fix it, but I'm not sure if it's the good fix
