RFR: 8354228: Parallel: Set correct minimum of InitialSurvivorRatio [v3]

[Albert Mingkun Yang]

> Updating the lower bound of InitialSurvivorRatio to match MinSurvivorRatio. The two removed test cases set conflicting Min and Intial SurvivorRatio, which, IMO, is an incorrect configuration, so I removed them.
> 
> Test: tier1-7
