SolochainDefaultConfig uses incorrect AccountData

Description of bug

In the definition of SolochainDefaultConfig:

			/// The default data to be stored in an account.
			type AccountData = crate::AccountInfo<Self::Nonce, ()>;

And the Account storage the frame_system pallet:

	/// The full account information for a particular account ID.
	#[pallet::storage]
	#[pallet::getter(fn account)]
	pub type Account<T: Config> = StorageMap<
		_,
		Blake2_128Concat,
		T::AccountId,
		AccountInfo<T::Nonce, T::AccountData>,
		ValueQuery,
	>;

which using the default config resolves to:

	/// The full account information for a particular account ID.
	#[pallet::storage]
	#[pallet::getter(fn account)]
	pub type Account<T: Config> = StorageMap<
		_,
		Blake2_128Concat,
		T::AccountId,
		//-- Note the duplication of AccountInfo --//
		AccountInfo<T::Nonce, AccountInfo<T::Nonce, ()>>,
		ValueQuery,
	>;

Not really a bug in the 'broken' sense but could be confusing for newcomers in that it will add an unused AccountInfo.

Probably makes most sense to just not default this at all and force the implementer to choose.
