langserver crashes if rootUri is not set

https://microsoft.github.io/language-server-protocol/specifications/lsp/3.17/specification/#initialize
The spec allows rootUri to be null, seems like langserver doesn't handle this

Opening a nim file outside of a nim project will make it crash

(Another issue is that crashes don't kill spawned nimsuggest server, so they remain alive)

I think I'm having a similar problem where it crashes when I try and open up a regular nim file: I get this error in my logs

[ERROR][2023-08-07 17:08:33] .../vim/lsp/rpc.lua:675    "rpc"    "/Users/saint/.nimble/bin/nimlangserver"    "stderr"    'Shutting down due to an error: Invalid scheme: , only "file" is supported\nutils.nim(87)            uriToPath\nasyncfutures.nim(389)    read\nasyncfutures.nim(389)    read\nasyncfutures.nim(389)    read\n???                      routeIter\nasyncfutures.nim(389)    read\nasyncfutures.nim(389)    read\n\n'

Also thanks for mentioning that crashes don't kill the spawned nimsuggest server, I was having loads of them on my system because of this!

Same issue for me as @sainttttt I'm still digging though.
