Maniphest Tasks: T13446: Allow username changes to change the letter case of an existing username
Commits: rPf5f2a0bc5696: Allow username changes which modify letter case to go through as valid

Summary

Fixes T13446. Currently, the validation logic here rejects a rename like "alice" to "ALICE" (which changes only letter case) but this is a permissible rename.

Allow collisions that collide with the same user to permit this rename.

Also, fix an issue where an empty rename was treated improperly.

Test Plan

Renamed "alice" to "ALICE".
- Before: username collision error.
- After: clean rename.
Renamed "alice" to "orange" (an existing user). Got an error.
Renamed "alice" to "", "!@#$", etc (invalid usernames). Got sensible errors.
