fix: allow to resume a running session

[aneojgurhem]

Motivation

Allow a running session to be resumed. It also allows to retry Resume RPC when errors occur. Does not put tasks back in Paused status when an error occur.

Description

• Remove the call to change the task status back to paused when there is an exception.
• Allow session status change to Running when the session is already Running

Testing

• Tests were performed with the GUI on the ArmoniK infrastructure. It fixes the issue when the Resume RPC times out. The tasks are not put back in Paused.

Impact

• Resume is working more reliably.
