test(navigation): poll for config propagation in buildCtrl

On CI, config.update() write is async and the next getConfiguration()
call may return a stale snapshot before the disk write flushes. Poll
until the base value is visible so getBasePath() resolves to the correct
tmpBase when getWeekFromURIAndConfig builds its path regex (T3/T4).
