Bug: Inconsistent handling of profile picture aspect ratio

[ThisGuyCodes]

Issue Summary

In the author profile and at the head of each post, the aspect ratio of the uploaded picture is unchanged, but in list view and in the top bar of the admin area, the profile picture appears to be 'squarified' before the circle is cut.

Steps to Reproduce

1. Upload a not-square profile picture
2. Observe the difference between the smaller circle in the top right of the admin area, and in the 'edit user' area within the admin area (other locations listed above work, this shows them all in one place.

This is a bug because...
It's inconsistent behaviour. I don't actually know if this is a theme issue or not, but I thought the admin area was not part of themes, so let's stick with that specifically.

Here are two screenshots, first from the admin area, observe the bigger bottom left, and the smaller (squished) top right:

And from the author posts-list page, a little bigger, but compage the top middle circle and the one next to the post name:

Hi @conslo, thanks for the great bug report!

This bug exists because in some places we use <img> tags, and background images in other places. Hey should all be backgrounds to preserve the aspect ratio.

I'll do a PR to fix very soon.
