Inconsistent $$MODULE for nested macro invocations

[cbuttner]

$$FILE $$LINE and $$FUNC all give info about the location of the initial macro invocation, but $$MODULE doesn't do that recursively for nested macro invocations.

module test::module_a;
import std::io;

macro print_builtins() {
  io::printfn("%s %s %s %s", $$FILE, $$LINE, $$FUNC, $$MODULE);
}

macro print_builtins_indirect() {
  print_builtins();
}

module test;

fn void main() {
  module_a::print_builtins();          // Prints macro_builtins.c3 22 main test
  module_a::print_builtins_indirect(); // Prints macro_builtins.c3 23 main test::module_a <----
}

This is fixed in dev now.

Perfect, thanks.
