Upload queue does not respect updated duplicate-handling settings.

Start by tracing the Android upload queue and how it reads duplicate-handling settings for items already queued. Reproduce the reported configuration change with queued photos, including the zero-byte case; done means queued uploads follow the current setting and do not incorrectly retry or replace files.
