Fix exception when reindexing deleted files.

This fixes #1 by setting in_trash=false (instead of None/null), when the the file is indexed.

Thanks for taking the time to report and fix the issue.

I think that just putting in_trash to false doesn't really solve the core of the problem. When doing that bags that have been marked as trash will reappear when indexing. It would be better if they stay in the trash.

The real problem here is that the list_bags call does not return bags that are in the trash. The best fix IMO would be to either call list_bags twice for both trash and non-trashed bags and join those lists, or modify the list_bags endpoint to be able to return both trashed and non-trashed bags.
