Remove the delay on calling trusts after inviting a player

[Zenion]

Yeah, that tracks - the delay starts on sending the invite, not on having the new member join. Though... you'd think it could have been just "you can't call trusts with party invitations pending."

Pretty sure it's the same duration as the timeout for accepting a party invite. This way you can't invite someone, wait, fill the party with trusts, then have them accept the invite to join thus making a party with too many people.

Changing party leaders also renders previous party invites inactive which is why the workaround works.

This seems the most likely explanation. Although, it has always been possible to over-invite a party, people who accept those invitations, it's just like it timed out.
