Remove cider-info-form eval hack that nREPL lookup / info ops deprecate

[jasalt]

This came up as issue while implementing nREPL server for Phel, where the (setq cider-info-form "") was required in Cider client config before lookup / info ops were added.

• defconst cider-info-form defined at https://github.com/clojure-emacs/cider/blob/master/cider-client.el#L527
• code checking if lookup / info ops are available https://github.com/clojure-emacs/cider/blob/master/cider-client.el#L561

Bozhidar commented "It’s strange that the op version doesn’t take precedence, though - like a bug on that front."
