Don't redirect to a microsite if a job is less than 30 minutes old [RD-44]

Retrieving the various DestinationManipulation objects right at the beginning of the view was unnecessary and could result in slowing down certain responses. It also would make it a little harder to finish this ticket, considering all of the special cases between when they were retrieved and when they were used. We were also not doing action_type=2 manipulations on anything but where action_type=1 is for microsite tags. This has been fixed, as it was somewhat of a requirement for this ticket.

Moving that bit of code to later on makes it much easier, and potentially speeding up certain requests is a happy coincidence.

All tests pass.
