"elided_named_lifetimes" lint in latest Rust nightly

[nazar-pc]

I have a function of this kind under async_trait:

    async fn contents(
        &self,
    ) -> Box<
          dyn Stream<Item = Result<ABC, FarmError>>
              + Unpin
              + Send
              + '_,
    > {
    }

In latest nightly I'm getting the following warning:

    |
111 |         &self,
    |         - lifetime `'life0` declared here
...
117 |                 + '_,
    |                   ^^ this elided lifetime gets resolved as `'life0`
    |
    = note: `#[warn(elided_named_lifetimes)]` on by default

It comes from generated code and I'm reluctant to actually writing 'life0 explicitly in such cases.

Would be nice to convert these it in the macro automatically.

This was fixed several weeks ago.
