[iOS] Only verify error code when link tapping fails.

The behavior of TapWebViewElementWithId() for links that close a
WebState is flaky on both simulator and device, regardless of whether
the Phase 1 UI Reboot flag is enabled.  This CL updates
FullscreenTestCase.testShowHeaderWhenChildTabCloses to check for the
error code only if the link tap is unsuccessful.

Note that the closure of the Tab and the visibility of the toolbar is
still verified after this occurs, so the test will still catch
fullscreen regressions after this change.

@cmasso This verification request is directed to... the test owner kkhorimoto?

Since this does not require manual verification, then I Kurt should verify.

Kurt, I am approving the merge upon verification of the fix in canary

It looks like there have not been any failures of this test since being reenabled on device, so I will cherry-pick now.
