Remove the delay on calling trusts after inviting a player

For those who don't know what's being talked about here:

Basically there is a potential issue with the trust system that is dependent on seperate systems, and the delay on summoning trusts after inviting party members was implemented as a measure to prevent that issue from occuring. Presumably if you summoned trusts quickly after inviting party members, it could cause undesirable/unexpected behaviors. But it seems like changing party leaders also mitigates this issue.
