test.There is a race condition where we flip the state from PENDING to ACTIVE and we heartbeat before storing on the KV.
This race condition became more evident after #5404 as now wen can heartbeat faster than the heartbeat interval.
The fix seems to be get the tokens from the lifecycle (not only the state) when performing the heartbeat.
