QF1003: reorder edits to respect LSP spec

LSP states that

> Text edits ranges must never overlap, that means no part of the original
> document must be manipulated by more than one edit. However, it is
> possible that multiple edits have the same start position: multiple
> inserts, or any number of inserts followed by a single remove or replace
> edit. If multiple inserts have the same position, the order in the array
> defines the order in which the inserted strings appear in the resulting
> text.
