fix(web): share picker titles match sidebar (name before summary) (#1219)

The /share route used a local getSessionTitle that preferred summary.text
over metadata.name, so Android share-target rows disagreed with the
session sidebar. Reuse @/lib/sessionTitle and lock the precedence with a
unit test. Closes tiann/hapi#1218 once upstream PR lands after dogfood.
