Don't unset Flip Mode when deleting all data in M&P

Whenever you delete all your save data, your settings aren't changed at
all, and you could resave them if you fiddled with a setting somewhere.
But the full game doesn't count Flip Mode as a setting, instead it
counts it as an unlock. This means deleting your save data would unset
Flip Mode in M&P, which would seem weird because in M&P it's just a
simple setting.

For consistency, Flip Mode shouldn't be unset when deleting save data in
M&P.
