String should be sanitized on hover

How are you using the lua-language-server?

Visual Studio Code Extension (sumneko.lua)

Which OS are you using?

Linux

What is the issue affecting?

Hover

Expected Behaviour

Consider the following code:

s = "one\ntwo\nthree"

When hovering over it, I'd expect to see the newline characters just as I wrote them in.

Actual Behaviour

Instead, the newlines and tabs would get "expanded", breaking the way the hover looks.

Reproduction steps

1. Create a string variable with newline (\n) or tab characters (\t)
2. hover over the variable

通过创建包含换行符或制表符的 Lua 字符串，并在 Visual Studio Code 扩展中将鼠标悬停在变量上来复现该问题。从 language server 的 hover 处理开始，跟踪字符串的格式化方式；当 hover 保留预期的转义字符且不破坏其布局时，即表示完成。
