Timeouts declining team invitation

This is blocking me from managing mailing list requests.

As we can see in the OOPS, we timeout because a few queries are repeated almost 400 times each. These queries are issued by IPerson.getSubTeams() and IPerson.getSuperTeams(), which are called by _cleanTeamParticipation(), which is, in turn, called by ITeamMembership.setStatus().

Since the act of declining a membership invitation is not actually deactivating an active membership we shouldn't need to call _cleanTeamParticipation(), so that'd be one way to avoid the timeouts.

We'd still need to find out why the methods are being called so many times, though.

Since we're kicking one team from another team, the code goes through all direct/indirect members of the team being kicked and tries to delete the TeamParticipation for that member on the super team. As we can see, the mailing-list-beta-testers team has 745 active members, which means our code will iterate through all of them attempting to delete the TP entries (if necessary), timing out after a few hundred iterations. :/

decreased importance and retargeted to 1.2.3 as having this on edge will provide a reasonable workaround for whoever experiences this.
