- Fix error where you couldn't list buckets if you didn't have access to all of them.
- Fix bug where listing with shell completion (page_sets/*) would only give the first file.
- Skip moving files if the destination bucket is the same as the source bucket.
- Remove checks that all files exist. If you use shell completion, you will include files that don't have hash files, just ignore them.


BUG=None.
TEST=None.
