Find references cannot find fun expressions using ?MODULE

[dszoboszlay]

Describe the bug
Consider the following sample module:

-module(foo).
-export([foo/0]).

foo() ->
  foo(),
  ?MODULE:foo(),
  fun foo/0,
  fun ?MODULE:foo/0,
  fun foo:foo/0,
  ok.

Find references for the function foo/0 shall find 5 references (in lines 5-9), but it only finds 4. It doesn't find the fun ?MODULE:foo/0 reference,

To Reproduce
Use above sample module.

Expected behavior
All 5 refernces are found by erlang_ls.

Actual behavior
Fun expressions containing the ?MODULE macro are not found.
