parallel routes: fix incorrect optimistic tree when there are multiple parallel routes (#48449)
This PR fixes parallel routes navigation with `prefetch={false}`. This
was broken because the optimistic tree created when navigating with
prefetching disabled resulted in a state where the router tree was
expecting an incorrect node to be rendered and suspended until the
imaginary data arrived.

The fix consists of updating the method that creates the optimistic tree
in order to bailout of the optimistic tree creation when there are
multiple parallel routes for the current node.
