Chore: ensure sidebar-expanded-mobile toggles

Revert: toggleCollapseSidebar should not be called on xs breakpoints

Adds rspec view tests that expect the nav sidebar
to have a class that will cause the nav sidebar
to be rendered collapsed with or without js.

Tests the nav sidebar on the admin, group,
instance statistics, user profile and project
sidebars.

Adds the sidebar-collapsed-mobile class to the haml layouts
and sets media queries to display the sidebar collapsed by
default for sreen sizes greater than `sm` and less than `lg`

Closes gitlab-ee#10021

See merge request gitlab-org/gitlab-ce!25688

When working on files in `app/graphql` the code correctly gets
autoloaded.

However, the redefined `Types::BaseField` would never receive the
`.accepts_definition` call, causing all queries after a reload to
fail. Calling `.accepts_definition` on its superclass makes sure the
reloaded version also has the `authorize` definition specified.
