[BUG] "personal information not registered" flag is set incorrectly with latest_flg == 1 when the data was set null

[purplesmoke05]

Describe the bug

• GET: /{token_address}/history/{ledger_id} returns some_personal_info_not_registered flag and it may be set incorrectly when the personal info was modified to null by the issuer.
• This is because there are some differences of the below two.

	# Retrieve personal info
	if token_contract.require_personal_info_registered is True:
	# Retrieve from contract storage
	personal_info = await personal_info_contract.get_info(
	account_address, default_value=None
	)
	if any(personal_info.values()) is False:
	personal_info_not_registered = True
	else:
	personal_info_not_registered = False
	else:
	# Do not retrieve contract data and return the default value
	personal_info = ContractPersonalInfoType().model_dump()
	personal_info_not_registered = True
	return personal_info, personal_info_not_registered
