Bug/absent data handling

[mokokom]

@willnwhite and I have fixed the issue with absent data and how to handle it in frontend during our pair programming. Also @ArunJose mentionned an issue with unsecure image link URL. This PR resolve this too by changing all image URL from HTTP to HTTPS.

On details page author info and publisher info are missing but it's shown in the card component.

Absent data handling on the card component works good.

Here are a few things I've noticed with the image:

• There is some grey area on the top and bottom of the image when the image size is smaller like in the first card.
• Instead of just showing a "image not available" I personally think it'd be better to show a placeholder image like this, or display nothing at all. Of course this is just preference

One other improvement that could be made is changing date format. It seems unclear what 1988/1/2 could mean. A better format would be like "2 Jan 1988".

In deploy preview the image links still aren't updated, it's still requesting http images and the warnings are still shown in console.

A search for "dragon force" shows that this fixes linked issue #72. I'm happy for this to be merged.

thank you for your feedback. @ArunJose, I will fix the issues you've mentioned. About HTTP URLs I made a mistake in calling the method on infoLink and I only called it in the Modal component and not in Cart. I think this should be fixed at the next PR.
