// update1 case:
// There's a team with the given name and the given ID
// and its founder has the right email address.
// Update its parameters if any are different.
// update2 case:
// There's a team with the given name and seti_id=0,
// and its founder has the right email address.
// Update its parameters if any are different,
// and set its seti_id.
// This handles the case where the team founder created the team

// conflict case:
// There's a team with the given name,
// and either it has the wrong ID
// or its founder has a different email address.
// Don't change anything.
// These semantics mean that:
// - A BOINC team can't change its name via this mechanism.
// This avoids pathological cases, e.g. if two teams swapped names,
// the updates would always fail.
// If a BOINC team wants to change its name,
// it must do it manually everywhere.
// - If a BOINC team changes its founder (or the founder changes email)
// they'll have to make this change manually on all projects.
// (this is better than a security vulnerability)
// - This mechanism can't be used to update the founder's
// account parameters on all projects
