When Querki is loading a Space, it should show the Space's name

(User Story, Closed -> Fixed, Priority: Critical, Test Status: No automated tests yet , Reported By Justin du Coeur, )
UX
Summary: Currently, we just keep showing "Loading Querki". But we probably have enough info to show the Space's name instead, and it would provide better feedback.
Suggested by Aaron. This is probably either quite easy, or very much not.
