Fix deployment initial status on creation

This patch makes sure that only auto deployments are started in
`PENDING` state. All manually launched deployments should start
with `UNEXECUTED` status, as the deployment execution gets created
right after. This will disallow the deployer manager to pick up
manual deployments.
