Aleksandr Bezobchuk b3aae970d8 blockchain v0: fix waitgroup data race (#5970) ...

## Description

Fixes the data race in usage of `WaitGroup`. Specifically, the case where we invoke `Wait` _before_ the first delta `Add` call when the current waitgroup counter is zero. See https://golang.org/pkg/sync/#WaitGroup.Add.

Still not sure how this manifests itself in a test since the reactor has to be stopped virtually immediately after being started (I think?).

Regardless, this is the appropriate fix.
