Social agent name should map to mission.

This should make Scenario.missions[] contain the social agent name instead of the mangled id.

It appears like this change causes a problem with combining groups of social agents.

The agent mission ids are marked like "social-actor-"+<group id>+<actor id>.

I can strip away the prefix "social-actor-" but then group id is still integrated. This is necessary because missions are combined between groups which may share the underlying actor name.

Given this case, I have now resorted to searching for the vehicles of interest in Scenario.missions.keys() using a substring match criteria. Hence, this PR may be closed. Thanks.

There is some consideration still here that the actor names should still be exactly named and unique between groups considering the actors are being combined across groups.
