Fastfix: Reverting Tour List Form Title Logic

Recent change to **CZ.Settings.isAuthorized && CZ.Authoring.isEnabled**
to display as "My Tours" is incorrect since this will show as My Tours
if the user has edit rights to other folks collections.

Moved the logic back to **CZ.Settings.isAuthorized &&
(CZ.Settings.userDisplayName === CZ.Settings.collectionOwner)** just for
the title. The other parts (create button and no tours warning) remain
under the existing if clause.
