Animation of Sidebar (video in here)

Edited the CSS of header and sidebar; added a new div of gitlab-logo-container to the html to make things easier.

The transition-duration is set to 0.3s and when the nav bar expands, it opens up over the text, essentially revealing hidden text.

Fix avatar tests to use banana_sample.gif

Fixes tests that were broken in f5e0e5c0 due to the purge of `gitlab_logo.png`.

See merge request !866

These fixes were performed automatically by Rubocop's `-a` flag.

Also MySQL complains when you change a field to be not null if any
existing records already have a null value, so this updates those rows.
