workspaces-display: Make workspacesView private

Browse Source 
WorkspacesDisplay was introduced to manage the workspace objects
and views; however, the overview still accesses the view held
by the workspacesDisplay directly, which is a bit odd.
Add some additional methods needed by the overview, and make the
view a private property.
