duplicate-set-field diagnostic when assigning a function to a table field

Nadie ha tomado este issue todavía.

### How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

### Which OS are you using?

Windows

### What is the issue affecting?

Diagnostics/Syntax Checking

### Expected Behaviour

No diagnostic warning on assignment because the variable has been 'cleared'.

### Actual Behaviour

The two info.func assignments that are "= function" get a Duplicate field 'func' (duplicate-set-field) diagnostic.
The info.func assignment "= l1" does not.
Scope depth does not seem to impact the diagnostic - within the same function.

Assignments to other fields that are string, integer, etc do not get the diagnostic.
FYI - the ".func" is expected in a library I cannot change.

### Reproduction steps

local function l1()
end
local function f1()
local info = {};
do
info = {};
info.notCheckable = true
info.func = function()
-- any code
end
end
info = {};
info.notCheckable = true
info.func = function()
-- any code
end
info = {};
info.notCheckable = true
info.func = l1
end

Comienza con los pasos para reproducirlo y el diagnóstico duplicate-set-field del subsistema Diagnostics/Syntax Checking. Compara las tres asignaciones de info.func en el fragmento de Lua proporcionado y, a continuación, localiza las pruebas existentes o la implementación del diagnóstico. Se considera terminado cuando las dos asignaciones de funciones inline ya no producen la advertencia indicada, mientras que la asignación de l1 y las demás comprobaciones de duplicate-field siguen estando cubiertas.
