Downgrade server binary version to v1.14.12

Seems like higher versions have some problems to connect to the chat
with and error
"E0909 18:12:42.996797 81468 interceptor.go:49] /exa.language_server_pb.LanguageServerService/AddTrackedWorkspace: file:///path/to/root/dir is hidden: ignore uri\n"

For some reason it detect any workspace root dir as hidden.
Also binary vesrions v.1.16+ break autocompletion too.
