Bugfix:router hydration duplication

[developit]

The router flicker fix from #358 and #337 didn't account for hydration, and was resulting in lazy() components being deopted out of hydration and their contents duplicated. This fixes that issue by only applying the VNode reorder workaround to client-side route transitions.
