try/except in orchestrator functions not being handled correctly

[cgillum]

There are two issues with try/except handling in orchestrator functions

1. Only the first task in an except block actually runs
2. The completed action in the except block always results in the original error being re-raised

The issue is that the internal state machine does not correctly clear the error status of a previously failed task, making it appear as if all subsequent tasks fail with the same error.
