3427: Restore arv-put's resume functionality.

The refactoring in 0d1a48e accidentally introduced a bug where arv-put
wipes its resume cache clean before building the uploader.  Because
the refactor always arranges `resume_cache = None` when the user
doesn't want to resume, we can fix the bug by just skipping the wipe.
Closes #3427.
