Merge branch 'remove-visibility-icons' into 'master'

Remove visibility icon from projects list on dashboard and group page

## Why?

Because

* visibility level show on project page anyway
* it does not have much value. Main purpose of project list on dashboard is navigation. Avatar + project name helps this goal. Visibility icon have no effect here
* it makes UI worse because it brings separation between project avatar and name
* without visibility icon we have more space for project name. Especially important for laptops
