[Fix clojure-emacs#1947] Reorder repl init after debugger init

When initializing the repl, we ask what namespace we are in by evaling code,
eg (eval "(str *ns*)"). However, enlighten mode hijacks eval messages in the
middleware and uses the debugger on them which causes an error if the debugger
is not yet initialized.
