Clear SessionState in TestJobManagerInitTimeoutTests TearDown

The persist/restore test writes synthetic jobs to SessionState, which
survives domain reloads and would be re-hydrated by TestJobManager's
[InitializeOnLoadMethod] hook. Flush the cleaned in-memory state back
to SessionState in TearDown so test artifacts don't leak across runs.
