Failing test for creation of ticket with default Constituency

RT's e092e23 changed ticket creation to expect that the user creating a
ticket would be able to load and see all the CFs passed to
RT::Ticket->Create.  This was done to avoid trying to add Transaction
CFs to Tickets, but means that RTIR can no longer pass in a default
value for the Constituency CF during ticket creation by non DutyTeam
members.

Unfortunately, RTIR needs to do this during RT::Ticket->Create, not
after, so that Scrips fired on On Create will have access to the
Constituency (such as all the core Correspondence scrips that change
$CorrespondAddress based on the value of Constituency).

Previously, no part of RTIR tested ticket creation except as DutyTeam
members.
Merge branch '3.2/constituency-regression-on-email-create' into 3.2.0-releng

Tests pass thanks to rt.git:ab7ea157
Can't delete it yet, flag people to better places

Ideally this will get parsed out into the UPGRADING files and then
deleted.
Update Module::Install
Require RT 4.2.9rc1 to install
