                           throws Inactive

Check the status of a transaction when the contact item uid is known. This method *must* only be called from replay_completion, since it relies upon this fact to differentiate between a committed or rolled back transaction in the event of finding no intentions list in the object store.

Returns:

the status of the transaction as known in the original process.

Throws:

Inactive - if the original process is no longer active.
