4.14.1 - Revert unnecessary command behavior change

What's Changed

Revert unnecessary command behavior change by @gwynne in #197

In a previous release, a change was made (by me) to how old Commands are integrated with AsyncCommands which was unnecessary, offers no tangible benefit, possibly has a (very small) speed penalty, and is one of a small number of potential sources of runtime stalls. This reverts said ill-advised change.

This patch was released by @gwynne
