Fixed a bug which caused StoreUUID to be unavailable on new installs.

[FIXED]     Removed the forced write coordination over the whole cloud store loading.
                - Initially intended to demark a sort of "transaction" for writing StoreUUID so as to force a conflict if another device committed a StoreUUID after we started tryLoadCloudStore but before we finished it.
                - Is causing trouble with coordinating read access to StoreUUID, looks like the coordinators are not actually coordinating read access anymore thus we don't block until StoreUUID becomes available locally for reading.
