Fixed in MR !637

Numeric usernames will not SEF now. It will instead just use the user id. The reason for this is reversing numeric username requires a DB query on the numeric value on reversal. This means if the value actually is a user id it costs a query for no reason in addition to risking matching a user by mistake when it actually is just the id. For example if the username is 123 and you're trying to access the profile of the user with id 123 and their username is for example Bob you have a serious issue of determining who you're trying to access.
