ctkPythonConsole - Fix autocomplete preference lookup

The condition to skip the current preference was incorrect. A pref
should be skipped:
  - if there are dots in pref and
  - if the completion has already more dots than the pref


The pref should be skip, breaking the loop couldn't give other pref
a chance to be compared.
