fix keychain reset not resetting wallet state

[natew]

Fixes bug with duplicated wallets after resetting keychain.

Testing flow:

1. Import wallets using seed or backup
2. Hit "Reset Keychain" and confirm
3. Import same seed or backup again
4. Make sure they look right - no duplicate wallets.

Should be good to follow up with this, but I think some of the MMKV instances being reset in clearMMKVStorage aren't necessary to reset when the intention is only to reset wallets/the keychain. May not be needed at all, or at least likely only specific STORAGE_IDS need clearing, e.g. FIRST_APP_LAUNCH:

rainbow/src/model/mmkv.ts

Lines 3 to 17 in d31b118

	export const STORAGE_IDS = {
	ACCOUNT: 'ACCOUNT',
	ASPECT_RATIO: 'ASPECT_RATIO',
	DOMINANT_COLOR: 'DOMINANT_COLOR',
	EXPERIMENTAL_CONFIG: 'EXPERIMENTAL_CONFIG',
	FIRST_APP_LAUNCH: 'FIRST_APP_LAUNCH',
	SWAPS_METADATA_STORAGE: 'SWAP_METADATA_STORAGE',
	LOCAL_STORAGE_ADAPTER: 'LOCAL_STORAGE_ADAPTER',
	NOTIFICATIONS: 'NOTIFICATIONS',
	RAINBOW_TOKEN_LIST: 'LEAN_RAINBOW_TOKEN_LIST',
	SHOWN_SWAP_RESET_WARNING: 'SHOWN_SWAP_RESET_WARNING',
	PROMO_CURRENTLY_SHOWN: 'PROMO_CURRENTLY_SHOWN',
	LAST_PROMO_SHEET_TIMESTAMP: 'LAST_PROMO_SHEET_TIMESTAMP',
	UNLOCKABLE_APP_ICONS: 'UNLOCKABLE_APP_ICONS',
	};

Also, assuming wipeKeychain is important to resetting wallets state fully, would be good to move that into clearWalletState (in the resetKeychain path) so that clearWalletState can cleanly be used on its own to fully reset, along with handling any necessary MMKV storage resetting.
