Link with www. on image results in a faulty link leading to 404-not found

[mjaragon]

Quick summary

The user added the link: www.noma.dk to an image in their email.

The link subscribers got was: https://noma.dk/?mailpoet_router&endpoint=track&action=click&data=WyIxMTEiLCJqZTZuOW05bTJnMGtrc3cwb2MwdzBjMGtzMDRja3c0OCIsIjEzIiwiOTJjMTY1MjFiYmFkIixmYWxzZV0

Which re-directed to: https://noma.dk/www.noma.dk, which doesn't exist and landed on a 404-not-found page (until we added a redirect)

Steps to reproduce

1. Add an image to an email
2. Add a link to the image starting with www. (no leading "https://" ), example: www.woocommerce.com (or www.noma.dk)
3. Send the email out
4. Click on the image in the email

What you expected to happen

Clicking on the link should take me to the link added to the image: www.noma.dk which should be https://noma.dk/

If I use the example "www.woocommerce.com" link instead, I'd expect to go to to the woocommerce site (https://woocommerce.com/)

What actually happened

Clicking on the link redirected me to https://noma.dk/www.noma.dk, which doesn't exist. (We have a redirect now, so it no longer goes to the 404 page)

When reproducing the error with a test link entered as www.woocommerce.com The link in the image of the email was: https://noma.dk/?mailpoet_router&endpoint=track&action=click&data=WyIxMTEiLCJqZTZuOW05bTJnMGtrc3cwb2MwdzBjMGtzMDRja3c0OCIsIjE3IiwiNjZjOTcwODFhMzQ2IixmYWxzZV0 Which redirects to: https://noma.dk/www.woocommerce.com (and a 404 error)

Context

This is a Team51 partner site hosted on Pressable, using MailPoet Sending Service to send the emails. Relevant P2 post about the project available here: https://wpspecialprojectsp2.wordpress.com/2021/11/17/noma/

Workaround details

Create a redirect for the faulty link. But this assumes that the user thinks about this before sending the email (in which case, they'd probably add the https:// in front of the link to avoid the issue anyway)
