Correctly Set Up EditorManager on New Workspaces (CodeEditApp#2114)

### Description

Adjusts the setup of EditorManager to always assign the `workspace`
property on all editors after restoring it. This creates duplicate work
when we have editors that successfully restore from a saved state, but
ensures we *always* set up the editor manager correctly even when an
error is thrown or there is no restoration data.

Adjusted UI tests to catch this.
