Merge #2508

2508: Code: don't check for ra_lsp_server on Windows r=matklad a=lnicola

Workaround for https://github.com/rust-analyzer/rust-analyzer/pull/2503#issuecomment-562980020.

~~(not yet tested on Windows)~~

We can't run `ra_lsp_server --version` right now because the server doesn't seem to handle arguments (so it hangs).
