### Expected behavior

When I save a file that has lsp mode , it should do the standard lsp things, format etc. but it should not insert compiler output into the file.

### Current behavior

Currently when I save a file there is a non zero change it will insert text into my file after it does its standard changes.

### Steps to reproduce

configure elixir +lsp in emacs, this occurs with lsp-mode as well as eglot and with lexical and elixir-lsp so any of these configs will be fine.
Open an elixir project.
make any trivial edit and save.
as it saves it rebuilds the project and formats.
often it will insert some of this compile into the file buffer and saves
an example

```
defmodule ApiWeb.Controller do
==> api
Compiling 2 files (.ex)
Generated api app
==> web_support
Compiling 4 files (.ex)
Generated web_support app
use ApiWeb, :controller
```

everything between the defmodule and the use line was inserted from the compiler.
