Fix incorrect Self path expand for inline_call

[A4-Tacks]

Fixes #19349

Example

trait Trait {
    fn f() -> Self;
}
struct Foo<'a>(&'a ());
impl<'a> Trait for Foo<'a> {
    fn f() -> Self { Self(&()) }
}
impl Foo<'_> {
    fn new() -> Self {
        Self::$0f()
    }
}

Before this PR

trait Trait {
    fn f() -> Self;
}
struct Foo<'a>(&'a ());
impl<'a> Trait for Foo<'a> {
    fn f() -> Self { Self(&()) }
}
impl Foo<'_> {
    fn new() -> Self {
        Foo<'a>(&())
    }
}

After this PR

trait Trait {
    fn f() -> Self;
}
struct Foo<'a>(&'a ());
impl<'a> Trait for Foo<'a> {
    fn f() -> Self { Self(&()) }
}
impl Foo<'_> {
    fn new() -> Self {
        Foo(&())
    }
}
