Only push scrolling down when Footer is present

[scazan]

This fixes vertical scrolling when there is no Footer below the content to see by conditionally adding the extra height. The screen was scrolling unnecessarily when the footer wasn't present. This makes sure that there is no scrolling when the footer is not present and the content does not go beyond the screen size.

Might want to check if this works well with #2805 still, both of which will hopefully merge today

Not sure if it's intentional or not but something changed with the 404 pages on small screens, they were displayed centered before and now they're aligned top: https://app.argos-ci.com/GitbookIO/gitbook/builds/2255/135184281
