`with` rewrite leaves empty `with` block behind in certain situations

[JesseHerrick]

Hello! 👋 Thanks for this awesome Elixir tool! We encountered an interesting bug while applying Styler to our codebase. It seems that in certain situations, Styler leaves behind an empty with block wrapping the result.

I plan on looking into this myself when I have a bit of time, but I figured creating the issue would be helpful for tracking in any case.

Versions

• Elixir: 1.16.0 and 1.17.2
• Styler: Latest commit c16d3a91e489d043738e2b3bf5c12b6e6357e80c

Example Input

This test case can replicate the issue:

test "bug in with rewrite" do
  assert_style(
    """
    with foo <- do_stuff(value),
         {:ok, result} <- do_more_stuff(bar, baz) do
      {:ok, result}
    end
    """,
    """
    foo = do_stuff(value)
    do_more_stuff(bar, baz)
    """
  )
end

Stacktrace / Current Behaviour

     Styling produced unexpected results
     expected:
       foo = do_stuff(value)
       do_more_stuff(bar, baz)
     styled:
       foo = do_stuff(value)

       with do
         do_more_stuff(bar, baz)
       end
