Make navigation-api/ tests resilient to starting with extra NavigationHistoryEntries

[chromium-wpt-export-bot]

When WPT are run in-browser or via wptrunner, there may be additional
session history entries when the test starts, so the tests shouldn't
assume that they start with navigation.entries().length == 1 or
navigation.currentEntry.index == 0.

This fixes all directories except navigate-event/ and
navigation-methods/, which had enough tests to deserve separate
treatment.

This is a workaround for #33590.

Looks like dispose-for-full-session-history.tentative.html is known to fail for Firefox in the same way (ReferenceError: navigation is not defined); this change is likely to be benign.

@KyleJu @DanielRyanSmith Admin merge? Thanks!

(@natechapin FYI: you can rerun the checks by closing and reopening the PR. Apparently it doesn't seem possible to remove the misleading "Re-run checks" button: #39458)
