SSP-1415 Allow pre-selection of inactive ref data in Intake

Reference data options also returned in unpaged lists now.

The changes to ChallengeTO objects are somewhat unrelated but
their Jackson annotations had to be changed to support testing.
They would have had to have been changed anyway (ignore
unrecognized field names). And the original patch that triggered
the problem (client now sends an "active" field, *was* related
to this ticket's parent ticket).
