the trait bound &mut Transaction<'_, Sqlite>: Executor<'_> is not satisfied

Bug Description

After updating to v0.7.0 I got this error

error[E0277]: the trait bound `&mut Transaction<'_, Sqlite>: Executor<'_>` is not satisfied
   --> file.rs:584:18
    |
584 |         .execute(&mut tx)
    |          ------- ^^^^^^^ the trait `Executor<'_>` is not implemented for `&mut Transaction<'_, Sqlite>`
    |          |
    |          required by a bound introduced by this call

    = help: the following other types implement trait `Executor<'c>`:
              <&'c mut AnyConnection as Executor<'c>>
              <&'c mut SqliteConnection as Executor<'c>>
              <&Pool<DB> as Executor<'p>>

151 |         E: Executor<'c, Database = DB>,
    |            ^^^^^^^^^^^^^^^^^^^^^^^^^^^ required by this bound in `Query::<'q, DB, A>::execute`

Minimal Reproduction

let mut tx = pool.begin().await.unwrap();

sqlx::query(r#"query"#,)
.execute(&mut tx)
.await
.unwrap();

Info

My bad, its mention in the CHANGELOG

The Executor impls for Transaction and PoolConnection have been deleted because they cannot exist in the new crate architecture without rewriting the Executor trait entirely.
To fix this breakage, simply add a dereference where an impl Executor is expected, as they both dereference to the inner connection type which will still implement it:
&mut transaction -> &mut *transaction
&mut connection -> &mut *connection
