**To Reproduce**

1. start a workflowrun
2. use vela-cli to restart the workflowrun
`vela workflow restart xxx --step xxx`
3. workflow will not handled by controller, and the log like this
`"Skip this reconcile" workflowrun="default/test-xxx" spanID="i-dv1uiiok"`

**Expected behavior**

**Screenshots**

**Workflow Version**
v0.6.0

**Cluster information**

**Additional context**

Start by reproducing the issue with `vela workflow restart xxx --step xxx` after starting a WorkflowRun, then inspect the workflow controller's reconcile path around the reported `Skip this reconcile` log. Done means a restarted running workflow is handled by the controller instead of remaining skipped.
