[Plugin: WordPress Importer] Generates Notices

notices on line 739 and 740.

The only reason I bring this up is because for Theme review, you must import the test data, and the theme can not generate notices with wp_debug on, but when you do, the plugin generates notices! It’d be nice to clean this up for the sake of the review process, thanks.
