Signature help doesn't work with some of IDE packages

It works with atom-typescript.

The strange thing is that if I show a signature help using atom-typescript, then if I do it in python, it works. There might be some race conditions somewhere.

I tested with back to atom-languageclient 0.99 and older versions of atom-ide-signature-help, and the behavior is the same. Not sure where to look for the problem, but the getSignatureHelp function returns an empty Array (if the code is not warmed up with TypeScript signature help!)
