Error when compiling with ocaml 4.11.1

[mockey]

Trying to compile the current version with ocaml 4.11.1 leads to an error:

File "src/context/common.ml", line 1105, characters 10-122:
1105 | 			| _ -> ExtList.List.find_map (fun t -> match t with TClassDecl c when c.cl_path = path -> Some c | _ -> None) m.m_types
                 ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Error: This expression has type Type.tclass option
       but an expression was expected of type Type.tclass = TType.tclass

See #10086 :)

After that PR, I found that extlib must be updated to 1.7.8 to avoid this error

opam upgrade extlib
