Use context name instead of key_uuid
context.key_uuid is only used as a suffix for the key files. There is already a unique ID associated with a the context; the context name includes a task ID, which is a UUID. This patch sets context.key_uuid to to context.name instead of generating a separate UUID As a result, get_short_key_uuid() is not needed.
