Make navigation-api/ tests resilient to starting with extra Navigatio…
Browse files Browse the repository at this point in the history 
…nHistoryEntries (#42232)

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.
