When running `LanguageServer` (in Neovim), the LSP log shows messages like

```julia
Downloading cache files...
…
Package FFTW (7a1cc6ca-52ef-59f5-83cd-3a7055c09341) is cached.
…
Done loading FFTW from cache...

```

Where does LanguageServer store its cache? I’m getting an unexplained “Missing reference”, and I’d like to check if nuking the cache has any effect.

One can set a path in the `LanguageServerInstance` constructor (`symserver_store_path`). If that is not set, it will be stored in a folder called `store` in the `SymbolServer` package folder. Which is really bad, we should migrate that to scratch spaces.
