Suppress the target band for laps that are just an unplanned continuation

Browse Source 
Confirmed against Garmin Connect's own workout view: a lap whose
IntensityType merely repeats the immediately preceding lap's (e.g. a second
"cool-down" lap right after the first) means the recording continued past
the end of that step, not that the workout prescribed a second target for
it. Only the first lap of such a run keeps its target/HR fields; the
continuation shows the actual trace with no expectation overlay. Doesn't
affect normal interval structure, since Effort/Recovery always alternate
and never appear back-to-back.
