Don't break startup at Games links, and reload titles in the iPhone app too

The fix review found the Games reload added to showPage() read `link`, which
the page declares later: opening Frame Control at #games, #library,
#sideloaded or #getgames threw at startup and skipped the rest of the setup.
And the iPhone app never watches the connection, so `link.s` stayed null and
titles still never reloaded there.

The reload now runs only when navigating to Games (the hashchange), where the
first load is already done, and doesn't depend on connection state; a failed
load shows its error in the list as Refresh did. tests/test_page_startup.py runs
the real showPage() at every page and section link with everything declared
later still uninitialised, and fails on the old line.
