doc for identifier in let definition is not found - regression

[ulugbekna]

Documentation for the identifier in a let definition is not found (but if the identifier is used later, the doc is still found.

Before:

./ocamlmerlin single document -position 2:5 -filename test.ml <<EOF
(** whatever *)
let id () = ()
EOF
{"class":"return","value":"whatever","notifications":[],"timing":{"clock":20,"cpu":4,"query":1,"pp":0,"reader":0,"ppx":0,"typer":2,"error":0}}

After 762e8bf (according to git bisect)

./ocamlmerlin single document -position 2:5 -filename test.ml <<EOF
(** whatever *)
let id () = ()
EOF
{"class":"return","value":"No documentation available","notifications":[],"timing":{"clock":20,"cpu":4,"query":1,"pp":0,"reader":0,"ppx":0,"typer":2,"error":0}}

---

./ocamlmerlin single document -position 4:10 -filename test.ml <<EOF
(** whatever *)
let id () = ()

let () = id ()
EOF
{"class":"return","value":"whatever","notifications":[],"timing":{"clock":26,"cpu":5,"query":2,"pp":0,"reader":0,"ppx":0,"typer":3,"error":0}}
