The deployments history should display the correct deployment account

Current Situation:  
When logged in with any other account than root and deployed a workflow, the deployments in the History tab show the deployment account as "root" only.

How to Reproduce:

• Login to the JOC Cockpit with any other user than root.
• Create and deploy workflow from the configuration tab.
• Switch to the History tab --> Deployments.
• The Account column only has a root user.

Desired Behavior:  

• The deployment history should display the correct deployment account.

Maintainers note
The working of the deployment user is as follows:

• Security Level Low
  • only credentials (Profile -> Signature Key Management) from root account will be used.
    • (root initially after installation or if configured differently - the default user account)
  • deployment is executed with this account, hence only the account name of the current default user will be recorded for the deployment history.
• Security Level Medium
  • each account has its own Credentials (Profile -> Signature Key Management)
  • deployment is executed with each separated account, hence different accounts are recorded for the deployment history.
• Security Level High
  • does not support automatic signing with stored credentials (only public keys or certificates are stored).
  • deployment is executed differently, each separate account will be recorded in the deployment history.
