Deleting a user shouldn't delete associated issues.
- "Associated" issues are issues the user has created + issues that the user is assigned to. - Issues that a user owns are transferred to a "Ghost User" (just a regular user with `state = 'ghost'` that is created when `User.ghost` is called). - Issues that a user is assigned to are moved to the "Unassigned" state. - Fix a spec failure in `profile_spec` — a spec was asserting that when a user is deleted, `User.count` decreases by 1. After this change, deleting a user creates (potentially) a ghost user, causing `User.count` not to change. The spec has been updated to look for the relevant user in the assertion.
