Goto autocompletion doesn't respect Editor: Insert Spaces setting

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?

Completion

Expected Behaviour

As can be seen in the images below, the autocompletion of goto continue will indent the ::continue:: line with four spaces, while my settings have Editor: insert spaces unchecked, which means it should insert a tab character instead.

Actual Behaviour

Note: in these images, the tab character is rendered as an arrow, while spaces are rendered as dots.

Reproduction steps

1. In VSCode, set your Editor: Insert Spaces setting to false
2. Try the following code:

local arr = {}

for k,v in pairs(arr) do
	if type(k) == "string" then
		goto continue
	end
    ::continue::
end

3. When you start typing goto continue, and select the popup, you'll get the four spaces indentation instead of tab on the ::continue:: line.

首先，在停用 Editor: Insert Spaces 並使用所示 Lua 程式碼片段的情況下，重現 VS Code 擴充功能中的 goto 補全行為，然後追蹤補全路徑。當 Editor: Insert Spaces 停用時，選取 goto continue 會使用定位字元而不是空格縮排標籤，即表示完成。
