Wrong DCA warning while using struct method defined in impl self.

[esdrubal]

While compiling the following:

struct MyStruct1 {}

impl MyStruct1 {
    fn foo() {}
}

fn main() {
    MyStruct1::foo();
}

We are getting this DCA warnings:

warning
 --> /home/marcos/Documents/dev/sway/test/src/e2e_vm_tests/test_programs/should_pass/dca/impl_self/src/main.sw:3:8
  |
1 | 
2 | 
3 | struct MyStruct1 {}
  |        --------- This struct is never used.

In rust there are no warnings emitted, as shown in this playground.

The current DCA graph to the example is as follows:
