Code review comment for lp://qastaging/~tomasgroth/openlp/pysword-import

I tried to do an import from a SWORD Bible I already have, and I got this error as the import itself started.

Traceback (most recent call last):
  File "/home/raoul/Projects/OpenLP/OpenLP/pysword-import/openlp/core/ui/wizard.py", line 217, in on_current_id_changed
