Fix import from vulyk: empty dicts

[dchaplinsky]

Because of conversion document->table->document, some of documents now has totally empty dicts.

Please address that problem.

During handling of the above exception, another exception occurred:

Not completely sure if that's related as it doesn't seem (and not supposed) to remove elements that contain a list, only list elements. Both cases (import and script) assign at least an empty list to the list-containing element as long as it was actually present in the source. Were there any files imported after the last successful analytics generation event?

In any case, I'll test this locally.

Were there any files imported after the last successful analytics generation event? Not to my memory.
