Mail address email constructor argument type incorrect

[DuckThom]

Preconditions (*)

Magento 2.3.3

Steps to reproduce (*)

>>> $address = new \Magento\Framework\Mail\Address(null, null);
=> Magento\Framework\Mail\Address {#17559}
>>> $address->getName();
=> null
>>> $address->getEmail();
TypeError: Return value of Magento/Framework/Mail/Address::getEmail() must be of the type string, null returned

Expected result (*)

Either one of:

• Instantiating the \Magento\Framework\Mail\Address class with a null value in the email parameter should not be possible, or;
• the getEmail method's return type should be nullable, the same as the constructor argument ( ?string )

Actual result (*)

Instantiating the Address class with a null email address is possible which will always cause the getEmail method to throw an exception as it's only allowed to return string values

TypeError: Return value of Magento/Framework/Mail/Address::getEmail() must be of the type string, null returned
