Remove the unconditional Default profile fallback

DeleteProfile no longer has a UI entry point, so the hardcoded
"Default" safety net it used to fall back to is no longer needed.
Unassigning a deleted profile now just clears the charProfile
mapping, and GetActiveProfileName/GetActiveClassSettings already
fall back to (and lazily recreate) the character's own auto-created
profile - the same thing that happens for a brand new character.
