Merge #8677

8677: Return ServerNotInitialized according to the spec r=kjeremy a=kjeremy

According to the spec we should return ServerNotInitialized if the server is waiting for an initialize request and something else comes in.
Upgrading to lsp-server 0.5.1 will do this and retry until the initialize request comes in.

Fixes #8581
