Adding a new workspace folder breaks things

How are you using the lua-language-server?

NeoVim

Which OS are you using?

Windows

What is the issue affecting?

Completion, Diagnostics/Syntax Checking, Hover, Libraries

Expected Behaviour

Addding new workspace folders should not break anything.

Actual Behaviour

Right now, adding a new workspace folder breaks two things, diagnostics and require statements:

• You can fix the diagnostic errors by hooking to the workspace/diagnostic/refresh handler to manually refresh it, but even then this is very unreliable and prone to not working:
  https://github.com/neovim/nvim-lspconfig/issues/2366

• require statements that refers to modules in the new workspace folder also does not resolve correctly (hovering over the module string will display the byte length, instead of the resolved path). This means that completions from the required module will also be missing. So far I can't find any way to fix this without restarting neovim entirely.

Other LSP servers doesn't have this problem. Adding a new workspace folder should just work without any additional steps.

Reproduction steps

1. Initialize the LSP server with a root directory
2. Add a new workspace folder using workspace/didChangeWorkspaceFolders
3. Opening a file from that workspace folder results in diagnostic errors and modules not being resolved correctly

首先重现报告的操作序列：使用根目录进行初始化，发送 workspace/didChangeWorkspaceFolders，并打开添加文件夹中的一个文件。随后调查 workspace/diagnostic/refresh 和 require 模块解析的行为。完成的标准是：在新的 workspace 中，diagnostics、悬停路径和 completions 均能正常工作，而无需重启 Neovim 或依赖手动刷新。
