Title: Move callee_id out of ast::expr

The `callee_id` in `ast::expr` in only used in a couple expression variants. This moves the `callee_id` into those branches to make it more clear when its should be used.

Also, it fixes a bug in a std::run test when there is a symlink in the path rust where was checked out.
