A reconcile that stops before the sync clears status.waves

Behavior#

convoy sets status.waves from each reconcile result. A reconcile that stops before the sync has no wave result. Examples are a source failure, a manual-mode hold and a cluster-wave hold. The status write then removes status.waves.

Effect#

status.waves can be empty while the objects of the waves are on the cluster. The wave start times are lost. This interacts with KB-7.

Workaround#

None known.

Fix direction#

Keep the previous status.waves when a reconcile has no wave result.
