Ephemeral runners unable to run workflows, only a single job

[dv01d]

Describe the bug
The first job executed on an ephemeral runner always triggers ACTIONS_RUNNER_HOOK_JOB_COMPLETED when this should be reserved for the end of a workflow.

To Reproduce
Steps to reproduce the behavior:

1. Create an ephemeral runner
2. have two jobs in a workflow depend on it
3. First job triggers ACTIONS_RUNNER_HOOK_JOB_COMPLETED, which deletes the runner
4. Second, or subsequent jobs either wait forever or die part way through as the ephemeral runner is deleted

Expected behavior
ACTIONS_RUNNER_HOOK_JOB_COMPLETED should be only triggered at the end of a designated workflow, not each job.

Runner Version and Platform

Latest, self hosted ephemeral

OS of the machine running the runner? OSX/Windows/Linux/...

What's not working?

Jobs hang, don't finish, or error out in a workflow in the UI.
