Revert "Raise NotFound error when retrieved by not uuid"

In the early days of OpenStack, user and project ids were not
uuids, but auto-incremented integers.

Since those early days, many operators fought long battles
against the unrelenting OpenStack behemoth.

Only those heroic operators who emerged victorious from the
brutal upgrade battles can show the scars of those integer
user and project ids like badges of honour.
