Nested property type lost when accessed from reference

Nobody has claimed this yet.

### 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?

Type Checking

### Expected Behaviour

``` ---@class A
local A = {}

---@class B
---@overload fun(): B
local B = {}

---@class C
---@overload fun(): C
local C = {}

A.property1 = B()

A.property1.property2 = C()

local refToB = A.property1

local refToC = refToB.property2
```

while the local `refToB` is correctly of type `B`, it no longer is aware of property2.


expected behavior would be that it is aware of the properties assigned to the instance.

### Actual Behaviour

presence of property is lost in the "instance" of object B (not definition).

### Reproduction steps

1. Go to '...'
2. Click '...'
3. See error '...'

Start with the Lua type-checking example in the issue and reproduce the missing property information through the assignments to A.property1, refToB, and refToC. Trace the relevant type-checking behavior until refToB retains property2 and refToC resolves as C; no repository file or test is named in the issue.
