Diagnostics can become stale when switching between <module>.lua and <module>/init.lua structures (such as when going back and forth between git branches)

What is the issue affecting?

Diagnostics/Syntax Checking

Expected Behaviour

Diagnostics should always be performed on the current version of a module that is on disk.

Actual Behaviour

When switching between two different ways of structuring the same module as described in the title, diagnostics can populate the Problems panel in VS Code with information about the version of the module that was on-disk before switching using a mechanism such as git checkout <branch>

Reproduction steps

1. Make sure Runtime Path includes ?.lua;?/init.lua
2. Create a module at foo.lua, populate it with working Lua code.
3. Create a new git branch
4. Refactor foo.lua to foo/init.lua
5. Various diagnostics will show up in the VS Code Problems Panel, such as duplicate definitions, missing annotations, etc. It almost looks like the LSP is trying to process both files at the same time.
