TriggerTest: Use new reference formats in MT and reverseViews tests
The counts reference format in test_trig_data_v1Dev_build
was changed in !38104 (merged). There are two tests comparing counts to the same reference - test_trig_data_v1Dev_MT_build
and test_trig_data_v1Dev_reverseViews_build
and the format update was missed for them. Fix by applying the same updates to these two tests.
Fixes ATR-22368 and is also relevant for ATR-22200 where this issue hides one that was there before.
