Bug description

dropimagesduetolackofannotation will delete all images in a labeled_data subfolder instead of only the ones that lack annotations when called on a folder with old style CollectedData that do not have the file path split across a multiindex.

was able to fix by adding:

    conversioncode.guarantee_multiindex_rows(DC)

before

annotatedimages = [fn[-1] for fn in DC.index]

between what are currently lines 225 adn 226 of trainingsetmanipulation.py.

I'm sorry i can't do a formal pull request - i haven't forked the code and gotten fully set up yet - will do.

Operating System
