[TECHNICAL SUPPORT] LPS-45618 Fixed SusbscriptionSender to handle not verified e-mail addresses as well

Hi Zsaga,

While I was fixing LPS-45580 I found this issue and it blocks the resolution of that issue. This one is quite simple. There are cases when an e-mail address where we want to send an e-mail is not assigned to a user. For this particular case when e-mail address verification is required, we send an e-mail to the new address which will be associated to the user when the sent link is invoked and the ticket number from the URL is posted with the verify_email_address form.

Should you have any concerns or questions, please let me know.
