fix(repl): prevent wrong-type-argument stringp nil

using chicken scheme 5.4.0 and geiser i was getting this
message repeatedly after every expression entered in repl

geiser-repl--output-filter: Wrong type argument: stringp, nil

in my case (geiser-con--connection-debug-prompt geiser-repl--connection)
evaluated to nil causing string-match-p to error out

(defun geiser-repl--matches-prompt-p (txt) ...
  txt was found to be the empty string most times ""

essential reduces to (string-match-p nil "")

so put some conditional pieces for txt is not a string,
if string is empty , no point checking since not a prompt

just use conjunction and to prevent string-match-p on nil on both
prompts
and use disjunction or to get next prompt type if first failed to match
