test(cypress): fix Has share activity race condition

Skip the re-navigation to /apps/files after createPublicShare.
The share is already recorded server-side (cy.wait('@createshare')) and
the sidebar is closed, so showActivityTab can be called directly.
Re-navigating caused NC to async-load the share badge on the file row,
which triggered a Vue re-render that closed the Actions menu before the
details entry could be clicked — failing even with a 10s timeout.
