Resolve the ParticipantCompletion race condition

This issue is documented here: JBTM-1429

In the documentation for JBTM-1429, we state that this issue is unlikely to happen in a distributed environment. This is true, however, the Compensations API is designed to work local-only as well as distributed over WS-BA. Therefore it is much more likely to happen in a production environment.

Therefore we need to remove this race condition. It can be done in a proprietary mannor as we are not interoperating with another implementation ion local-only mode. When distributing the transaction we fall back to the standard protocol that is susceptible to the race condition. However, as we stated in the docs, this condition is unlikely to manifest in a distributed environment.
