A user hit an issue on an iPhone 5s. Device transfer would fail because their app group was missing the ProfileAvatars directory. This directory is lazily created as a post-launch job at background QoS. It's not too big of a deal and it'll be created on demand if necessary. The 5s was probably CPU constrained enough to never have a chance to run any background jobs. The fix is to just have our recursive filesystem traversal ignore any unknown directory errors. This is only used in a couple places and the behavior makes sense in each place.
