`convert_tuple_struct_to_named_struct` produces intersecting edits when a macro expands a field access twice

rust-analyzer version: 0.3.2929-standalone (panic message below is from a source build of master with force-always-assert; on the release build the assist silently does nothing and only logs the error)

code snippet to reproduce:

macro_rules! m { ($e:expr) => { ($e, $e) }; }

struct T(i32);

fn main() {
    let u = T(1);
    m!(u.0);
}

reproduce:
cursor on T in struct T(i32);
Convert to named struct

expected:
struct T { field1: i32 } with the usage rewritten to m!(u.field1);, or the field reference inside the macro left alone. either way no crash.

actual:
on the release build the assist is offered, applies nothing, and logs the error. on a build with debug assertions the request handler panics:

request handler panicked: some replace change ranges intersect!
left change:  ReplaceWithMany(Token(INT_NUMBER@461..462 "0"), [Node(NAME@0..6)]) 0field1
equals
right change: ReplaceWithMany(Token(INT_NUMBER@461..462 "0"), [Node(NAME@0..6)]) 0field1

panicked at crates/syntax/src/syntax_editor/edit_algo.rs:478:5:
some replace change ranges intersect!

cause:
the macro expands $e twice, so the field-reference search returns two FileReferences for the single 0 token in the source. edit_field_references maps both back to the same source token and registers two identical ReplaceWithMany changes, tripping stdx::always!(false, "some replace change ranges intersect!") in edit_algo.rs — the whole edit is discarded.

note:
same root cause as the destructure_tuple_binding / destructure_struct_binding / convert_named_struct_to_tuple_struct issues. related but distinct from #22094 (that one hits the unimplemented! in the dependent-change resolver at edit_algo.rs:298; this one hits the disjointness check at :478).
