Many templates use the company logo that is set by default on
database creation. As that logo is clearly a placeholder and the user
isn't necesserely prompted to update it. It's possible for a user to
inadvertently start sending emails with "your logo" placeholders
plastered all over.
This removes the default logo of the company and removes it from
templates conditionally.
The logo isn't simply replaced with a transparent PNG as the templates
set a fixed height for the logo, which would look weird.
