[sshyub]

Describe the bug
workflow can't be recovered if delete or replace action fails.

To Reproduce
Given the example that has verify, push, commit, reset stages, workflow can be recovered in the following cases:

• verify (create) -> reset (delete)
• verify (create) -> push (update)-> reset (delete)

but workflow can't be recovered if one of the actions in commit stage fails.
