Title: Fix for 'Revisions only show in one tab'.

Fix for ajaxorg/cloud9infra#2517.

Upon switching tab, the revisions data model is updated but not populated, which causes the list to never be filled, except for if the user triggers it by checking the 'Show all file changes' checkbox, which indirectly triggers a call to `populateModel`.

Now the `show` method makes sure that the current model is populated.
