[Fix] Errors should not "unsuspend" a transition (#22423)

If an error is thrown during a transition where we would have otherwise
suspended without showing a fallback (i.e. during a refresh), we should
still suspend.

The current behavior is that the error will force the fallback to
appear, even if it's completely unrelated to the component that errored,
which breaks the contract of `startTransition`.
