Bug description

The image rendered under /apps/theming/icon does not consider the original aspect ratio of an uploaded logo. It makes it square.

Steps to reproduce

1. Go to https://yournextcloud.com/settings/admin/theming and upload a non-square image under Logo
2. See that the generated image under https://yournextcloud.com/apps/theming/icon is deformed:

Expected behavior

The generated image should keep the aspect ratio of the original logo and scale it propotionally.
