`__call` metamethod return type ignored

This works in Intelij but not with your extension

---@class Test
local Test = {
	someval=404
}
---@return Test
function Test:__call() end
setmetatable(Test, Test)

local t = Test()
-- No completion for the following
t.

As i note it seems that setmetatable might not even be accounted for and that only the fact __call is in the same table makes it work in InteliJ, though i am not sure.

首先重现 Lua 代码片段，并检查 local t = Test() 和 t. 后的补全。跟踪扩展如何推断 __call 的返回类型，以及是否会考虑 setmetatable；当返回的 Test 类型能够提供 someval 补全时即完成。
