Ensure there is an $architecture on updates if the old manifest is not found
Ensure there is an $architecture on updates if the old manifest is not found

If the old manifest is not available no $architecture is loaded
resulting in an error while installing the update.

This happend for example for php if there was a conf directory along the
versions. `conf` will be picked up as latest version but there is no
manifest inside. #1185
